Abstract

Preceding a core-collapse supernova, various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive stars. Among them, the electron antineutrinos are potentially detectable by terrestrial neutrino experiments such as KamLAND and Super-Kamiokande via inverse beta decay interactions. Once these pre-supernova neutrinos are observed, an early warning of the upcoming core-collapse supernova can be provided. In light of this, KamLAND and Super-Kamiokande, both located in the Kamioka mine in Japan, have been monitoring pre-supernova neutrinos since 2015 and 2021, respectively. Recently, we performed a joint study between KamLAND and Super-Kamiokande on pre-supernova neutrino detection. A pre-supernova alert system combining the KamLAND detector and the Super-Kamiokande detector was developed and put into operation, which can provide a supernova alert to the astrophysics community. Fully leveraging the complementary properties of these two detectors, the combined alert is expected to resolve a pre-supernova neutrino signal from a 15 M$_{\odot}$ star within 510 pc of the Earth, at a significance level corresponding to a false alarm rate of no more than 1 per century. For a Betelgeuse-like model with optimistic parameters, it can provide early warnings up to 12 hours in advance., Comment: Resubmitted to ApJ. 22 pages, 16 figures, for more information about the combined pre-supernova alert system, see https://www.lowbg.org/presnalarm/

Abstract

With the discovery of non-zero value of $\theta_{13}$ mixing angle, the next generation of long-baseline neutrino (LBN) experiments offers the possibility of obtaining statistically significant samples of muon and electron neutrinos and anti-neutrinos with large oscillation effects. In this document we intend to highlight the importance of Near Detector facilities in LBN experiments to both constrain the systematic uncertainties affecting oscillation analyses but also to perform, thanks to their close location, measurements of broad benefit for LBN physics goals. A strong European contribution to these efforts is possible., Comment: Document submitted to the European Strategy For European Particle Physics

Abstract

This document summarizes the conclusions of the Neutrino Town Meeting held at CERN in October 2018 to review the neutrino field at large with the aim of defining a strategy for accelerator-based neutrino physics in Europe. The importance of the field across its many complementary components is stressed. Recommendations are presented regarding the accelerator based neutrino physics, pertinent to the European Strategy for Particle Physics. We address in particular i) the role of CERN and its neutrino platform, ii) the importance of ancillary neutrino cross-section experiments, and iii) the capability of fixed target experiments as well as present and future high energy colliders to search for the possible manifestations of neutrino mass generation mechanisms., Comment: 10+6 pages; Summary Document of the European Neutrino Town Meeting, Oct 22-24 at CERN; editors: Alain Blondel, Albert De Roeck, Joachim Kopp; v2: references added

Abstract

The presentations, discussions and findings from the inaugural `PhyStat-$\nu$' workshop held at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU) near Tokyo in 2016 are described. PhyStat-$\nu$ was the first workshop to focus solely on statistical issues across the broad range of modern neutrino physics, bringing together physicists who are active in the analysis of neutrino data with experts in statistics to explore statistical issues in the field. It is a goal of PhyStat-$\nu$ to help serve the neutrino physics community by providing a forum within which such statistical issues can be discussed and disseminated broadly. This paper is adapted from a summary document that was initially circulated amongst the participants soon after the workshop. Another PhyStat-$\nu$ workshop is being held at CERN in January 2019, building on the discussions in 2016. Advances in experimental neutrino physics in recent years have led to much larger datasets and more diversity in the properties of neutrinos that are being investigated. The discussions here raised several areas where improved statistical errors and more complicated interpretations of the data require statistical methods to be revisited, as well as topics where broader discussions between experimentalists, phenomenologists and theorists will required, which are summarised here. It is important to record the state of the field as it stands today, as much is expected to change over the coming years, including the emergence of more inter-collaborational studies and increasing sophistication in global parameter fitting and model selection methods. The document is also intended to serve as a reference for pedagogical material for those who are new to the use of modern statistical techniques to describe experimental data, as well as those who are well-versed in these techniques and wish to apply them to new data.

Abstract

We describe a procedure to tune the charged hadron multiplicities for deep inelastic events produced by the NEUT neutrino interaction generator. This tuning uses a model based on Koba-Nielsen-Olesen scaling, whose parameters are obtained by fitting multiplicity data from deuterium bubble chamber experiments. After tuning, the multiplicities of the events generated by NEUT are found to be in good agreement with the measurements from the bubble chamber experiments., Comment: 4 pages, 3 figures, proceedings for a poster presented at NuINT2015

Abstract

An Optical Transition Radiation monitor has been developed for the proton beam-line of the T2K long base-line neutrino oscillation experiment. The monitor operates in the highly radioactive environment in proximity to the T2K target. It uses optical transition radiation, the light emitted from a thin metallic foil when the charged beam passes through it, to form a 2D image of a 30 GeV proton beam. One of its key features is an optical system capable of transporting the light over a large distance out of the harsh environment near the target to a lower radiation area where it is possible to operate a camera to capture this light. The monitor measures the proton beam position and width with a precision of better than 500 {\mu}m, meeting the physics requirements of the T2K experiment., Comment: 17 pages, 21 figures, Submitted to NIM A

7. First Oscillation Results for the T2K Experiment

Author

Subjects
High Energy Physics - Experiment
Abstract

T2K is a long baseline high intensity neutrino oscillation experiment employing an off-axis design to search for the as yet unobserved appearance of \nu_e neutrinos in a \nu_{\mu} beam. The neutrino beam originates at the J-PARC facility in Tokai, Japan and the Super-Kamiokande (SK) detector, located 295 km away, measures the composition of the oscillated beam. The SK data are searched for an excess of \nu_e, constraining the allowed parameter space of sin^2(2\theta_{13}), the parameter governing the amplitude of oscillations from \nu_{\mu} to \nu_e. This amplitude is of particular interest since it also modulates the amplitude of CP violating terms in the lepton mixing matrix. This paper presents results from the first T2K physics run in 2010 with 3.23\times10^19 protons on target., Comment: 6 pages, talk given at Recontres de Moriond EW 2011, to be published in conference proceedings

Abstract

A Beam Induced Fluorescence (BIF) profile monitor is under development at the J-PARC neutrino extraction beamline, where neutrinos are produced using 30 GeV protons from the J-PARC MR accelerator. Towards the goal of continuously and non-destructively measuring the 1.3MW proton beam profile spill-by-spill using fluorescence from proton interactions with injected gas, a full working prototype monitor was installed in the beamline in 2019. The prototype includes a scheme for pulsed injection of N₂ gas into the ultra-high vacuum beampipe and two optical readout arms, a conventional one using an Image Intensifier coupled to a CID camera, along with an array of optical fibers coupled to a Multi-Pixel Photon Counter array. Initial beam tests of the system were carried out in early 2020, and BIF light was successfully observed in both optical systems. Details of the prototype monitor, along with first proton beam profile measurement results, will be shown. Improvement plans towards continuous operation of the new profile monitor will also be discussed., Proceedings of the 9th International Beam Instrumentation Conference, IBIC2020, Santos, Brazil

Abstract

A Beam Induced Fluorescence (BIF) monitor is being developed as an essential part of the monitor update toward MW beam power operation at the J-PARC neutrino beamline. By measuring the fluorescence light from proton-gas interactions, the BIF monitor will be used as a continuous and non-destructive diagnostic tool for monitoring the proton beam profile spill-by-spill, with position and width precision on the order of 200 µm. The main challenge lies in collecting a sufficient amount of fluorescence light for the beam profile reconstruction while controlling the beam-induced noise with the current beamline configuration. A study is presented with a particular focus on the optical system under development, which allows us to transport fluorescence light away from the high radiation environment near the proton beamline and detect the optical signal with a Multi-Pixel Photon-Counter-based fast readout., Proceedings of the 7\textsuperscript{th} Int.

Abstract

A Beam Induced Fluorescence (BIF) monitor is under development for non-destructively monitoring the future MW-power proton beam at the neutrino extraction beamline at J-PARC. The §I{30}{GeV} protons are bombarded onto a graphite target, producing one of the most intense neutrino beams in the world for the Tokai-to-Kamioka (T2K) long-baseline neutrino oscillation experiment, where beam profile monitoring is essential for protecting beamline equipment and understanding the neutrino flux. For the BIF monitor, gas is injected into the beam pipe and the spatial distribution of the fluorescence light induced by proton-gas interactions is measured, allowing us to continuously and non-destructively monitor the proton beam profile. However, the specifications of the beamline require us to carefully control the gas localization by pulsed injection. Radiation hardness of all monitor components and profile distortion caused by space charge effects must also be considered. We will show how to address these challenges and realize a working prototype., Proceedings of the 8th International Beam Instrumentation Conference, IBIC2019, Malmö, Sweden

Abstract

Proton beam monitoring is essential for the J-PARC neutrino beamline, where neutrinos are produced by the collision of 30 GeV protons with a long carbon target. Along with continued upgrades to the J-PARC beam power, from the current 420 kW to 1.3+ MW, there is also a requirement for monitor upgrades. A Beam Induced Fluorescence monitor is under development, which would continuously and non-destructively measure the proton beam profile spill-by-spill by measuring fluorescence light from proton interactions with gas injected into the beamline. Monitor design is constrained by the J-PARC neutrino beamline configuration, where a major challenge will be getting sufficient signal to precisely reconstruct the proton beam profile. R&D for a pulsed gas injection system is under way, where injected gas uniformity and vacuum pump lifetime are main concerns. Design of a light detection system is also under way, where light transport away from the high radiation environment near the proton beamline, as well as fast detection down to very low light levels, are essential., Proceedings of the 5th Int.

Abstract

This document summarizes the conclusions of the Neutrino Town Meeting held at CERN in October 2018 to review the neutrino field at large with the aim of defining a strategy for accelerator-based neutrino physics in Europe. The importance of the field across its many complementary components is stressed. Recommendations are presented regarding the accelerator based neutrino physics, pertinent to the European Strategy for Particle Physics. We address in particular i) the role of CERN and its neutrino platform, ii) the importance of ancillary neutrino cross-section experiments, and iii) the capability of fixed target experiments as well as present and future high energy colliders to search for the possible manifestations of neutrino mass generation mechanisms., Comment: 10+6 pages; Summary Document of the European Neutrino Town Meeting, Oct 22-24 at CERN; editors: Alain Blondel, Albert De Roeck, Joachim Kopp; v2: references added

Abstract

The presentations, discussions and findings from the inaugural `PhyStat-$\nu$' workshop held at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU) near Tokyo in 2016 are described. PhyStat-$\nu$ was the first workshop to focus solely on statistical issues across the broad range of modern neutrino physics, bringing together physicists who are active in the analysis of neutrino data with experts in statistics to explore statistical issues in the field. It is a goal of PhyStat-$\nu$ to help serve the neutrino physics community by providing a forum within which such statistical issues can be discussed and disseminated broadly. This paper is adapted from a summary document that was initially circulated amongst the participants soon after the workshop. Another PhyStat-$\nu$ workshop is being held at CERN in January 2019, building on the discussions in 2016. Advances in experimental neutrino physics in recent years have led to much larger datasets and more diversity in the properties of neutrinos that are being investigated. The discussions here raised several areas where improved statistical errors and more complicated interpretations of the data require statistical methods to be revisited, as well as topics where broader discussions between experimentalists, phenomenologists and theorists will required, which are summarised here. It is important to record the state of the field as it stands today, as much is expected to change over the coming years, including the emergence of more inter-collaborational studies and increasing sophistication in global parameter fitting and model selection methods. The document is also intended to serve as a reference for pedagogical material for those who are new to the use of modern statistical techniques to describe experimental data, as well as those who are well-versed in these techniques and wish to apply them to new data.

Abstract

Recent measurements at the T2K experiment indicate that CP violation in neutrino mixing may be observed in the future by long-baseline neutrino oscillation experiments. We explore the physics program of an extension to the currently approved T2K running of $7.8\times 10^{21}$ protons-on-target to $20\times 10^{21}$ protons-on-target,aiming at initial observation of CP violation with 3$\,\sigma$ or higher significance for the case of maximum CP violation. With accelerator and beam line upgrades, as well as analysis improvements, this program would occur before the next generation of long-baseline neutrino oscillation experiments that are expected to start operation in 2026., Comment: 18 pages, 4 figures

We propose an extension to the currently approved T2K running from $7.8\times 10^{21}~\mbox{POT}$ to $20\times 10^{21}~\mbox{POT}$, aiming at initial observation of CP violation with 3$\,\sigma$ or higher significance for the case of maximum CP violation. The program also contains a measurement of mixing parameters, $\theta_{23}$ and $\Delta m^2_{32}$, with a precision of 1.7$^\circ$ or better and 1%, respectively.

Abstract

T2K is an experiment designed to study the ways in which neutrinos evolve as they propagate through space. The experiment uses an artificial beam of muon neutrinos, produced at the J-PARC facility in Japan. The spontaneous mixing of these beam neutrinos with other flavours is measured after 295 kilometres, at the location of the Super-Kamiokande detector. The initial beam composition is measured after 280 metres, using a combination of two near detectors. T2K is optimised for measurements of electron neutrino appearance, and muon neutrino survival. Essential for these measurements is a detailed knowledge of the initial beam composition, before neutrino oscillations had occurred. The production of intense neutrino beams at accelerator facilities is challenging, and requires exceptional understanding of chains of hadronic interactions initiated within thick targets. Most of T2K neutrinos are produced from in-flight decays of focused pions and kaons, emitted from an extended graphite target (90 cm) bombarded with a 30 GeV proton beam. Besides internal constraints from near detector data, T2K relies on hadron production measurements collected by other experiments, most importantly NA61, for accurate modelling of the initial neutrino flux. This thesis presents a new T2K neutrino flux prediction, using the NA61 replica-target dataset from 2009. The earlier flux prediction relied on NA61 measurements collected with protons incident on a thin graphite target (2 cm). The following analysis incorporates NA61 data collected on the full length replica of the T2K target in 2009. In light of this new data, the flux calculation technique has been modified. A dramatic reduction in the unoscillated muon neutrino fractional flux uncertainty has been achieved, from ~10% to ~5% around the T2K flux peak. The impact of the improved flux prediction on oscillation measurements has been examined, by performing separate fits to ND280 data, and joint ND280 and Super-K data, in the well-established Bayesian Markov Chain Monte Carlo analysis framework.

28. Measurement of the Bc± Meson Lifetime Using Bc±->J/ψ+l±+X Decays

Author

Hartz, Mark

Abstract

This thesis describes a measurement of the average proper decay time of the B±c mesons, the ground state of bottom and charm quark bound states. The lifetime measurement is carried out in the decay modes B±c -> J/ψ+e±+X and B±c -> J/ψ+μ±+X, where the J/ψ decays as J/ψ -> μ+μ- and the X are unmeasured particles such as νe or νμ. The data are collect by the CDF II detector which measures the properties of particles created in sqrt(s)=1.96 TeV proton/antiproton collisions delivered by the Fermilab Tevatron. This measurement uses ~fb-1 of integrated luminosity. The measured average proper decay time of B±c mesons, τ = 0.475+0.053-0.049(stat.)±0.018(syst.) ps, is competitive with the most precise measurements in the world and confirms previous measurements and theoretical predictions.

Abstract

The radioactivity background are among the most dangerous background for low energy neutrino analysis in Super-Kamiokande (SK), like the solar neutrino analysis. Among them, the main contribution is coming from $^{222}$Rn, which is spread in the detector's water due to the water source and to the photo multiplier (PMT) emanations. Up to now, its exact distribution in the detector was not known. Using our knowledge of the radon concentration in the detector water, and the SK-IV solar data, we developed a model of the radon distribution in the detector. The uncertainty on the Rn concentration associated with this model was estimated to be $\sim0.1$ mBq/m$^{3}$

Abstract

Super-Kamiokande (SK) is a 50-kt water Cherenkov detector, instrumented with $\sim 13$k photo-multipliers and running since 1996. It is sensitive to neutrinos with energies ranging from 4.5 MeV to several TeV. A new framework has been developed for the follow-up of gravitational wave (GW) alerts issued by the LIGO-Virgo collaboration (LVC). Neutrinos are searched for, using a 1000-second time window centered on the alert time and in both SK low-energy and high-energy samples. Such observation can then be used to constrain the neutrino emission from the GW source. The significance of potential signals has been obtained by comparing neutrino direction with the localization of the GW. The computation of limits on incoming neutrino flux and on the total energy emitted in neutrinos by the source has been performed for the different neutrino flavors. The results using the LVC GWTC-2 catalog (covering O3a period) are presented, as well as the outlooks for the future real-time public release of follow-ups for the O4 period (in 2022) and beyond.
