Abstract

The decay K + → π + v v ¯ , with a very precisely predicted branching ratio of less than 10−10, is one of the best candidates to reveal indirect effects of new physics at the highest mass scales. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the K + → π + v v ¯ with a decay-in-flight technique, novel for this channel. NA62 took data in 2016, 2017 and 2018. Statistics collected in 2016 allows NA62 to reach the Standard Model sensitivity for K + → π + v v ¯ , entering the domain of 10−10 single event sensitivity and showing the proof of principle of the experiment. The analysis data is reviewed and the preliminary result from the 2016 data set presented.

Abstract

The NA62 experiment at the CERN SPS aims at measuring the ultra-rare decay $K^+ \to \pi^+ \nu \bar{\nu}$ with 10% accuracy. This can be achieved by detecting about 100 Standard Model events with 10% background in 2-3 years of data taking. The experiment consists of a large number of subsystems dedicated to the detection of the incoming kaon and outgoing pion and also focusing on particle identification and vetoing capabilities. Run Control has been designed to link their trigger and data acquisition systems in a single central application easily controllable by educated but non-expert operators. The application has been continuously evolving over time, integrating new equipments and taking into account requirements and feedback from operation. Future development includes a more automatized system integrating the knowledge acquired during the operation of the experiment., Comment: 4 pages, 1 figure, Poster at Kaon 2016 conference, 14-17 September 2016, Birmingham

Abstract

The NA48/2 experiment at CERN collected in 2003-2004 a large sample of charged kaon decays with multiple charged particles in the final state. A new upper limit on the rate of the lepton number violating decay obtained from this sample is reported. Moreover searches for two-body resonances in the K ± → πμμ, decays (including heavy neutral leptons and inflatons) in the accessible range of masses and lifetimes are presented. During the 2016 run the NA62 experiment has collected data with a dedicated trigger for kaon decays with two muons in the final state. Preliminary results on the statistics collected during a period of two weeks for the decay K + → π+μ+μ− will be presented. The NA62 experiment has good potential for the studies of rare K + decays in addition to its main goal, the measurement of the branching ratio of the decay .

Abstract

In 2007 the NA62 experiment at CERN collected a large sample of charged kaon decays with a highly efficient trigger selecting events with electrons in the final state. The kaon beam represents a rich source of tagged neutral pion decays in vacuum. The electromagnetic transition form factor slope of the π(0) in the time-like region has been measured from about 10(6) fully reconstructed π(0) Dalitz decays collected in 2007. The preliminary result a = (3.68 ± 0.51(stat) ± 0.25(syst)) × 10(-2) is the most precise to date. This value is compatible with theoretical expectations and consistent with the previous measurements.

Abstract

The NA62 experiment at CERN SPS will soon start taking data to measure the ultra-rare decay K+ → π+v. The requirement to reach a rejection factor of 1012 can be obtained with a large number of VETO and particle identification detectors as well as momentum measurement spectrometers. All components are included in the Trigger and/or Data Acquisition system. The RunControl has been designed to centrally link them to achieve their control and monitoring while still allowing non-experts shifters to run the experiment easily.

Abstract

The NA62 experiment at the CERN SPS is aimed at measuring the branching fraction of the ultrarare decay K+ → π+v with ~10% precision by collecting ~1013 kaon decays in two years of data taking. This amount of data will allow to carry out a wide program of searching for rare and forbidden (within the Standard Model) K+ and π0 decays, including sterile neutrinos, lepton flavor violating modes, exotic particles (e.g. "dark photons"). The expected performances of the NA62 setup will allow to improve existing limits for several decay modes.

Abstract

The NA62 experiment at the CERN SPS aims to measure the branching ratio of the very rare kaon decay K+ → π+v, collecting 0(100) events with a 10% background in 2 years of data taking. A modified CEDAR (Cherenkov Detector with Achromatic Ring focus), named KTAG (Kaon TAGger), will be used to positively identify kaons in the beam, to reduce the background from scattered pions.

Abstract

The Measurement of the helicity suppressed ratio of charged kaon leptonic decay rates RK = Γ (K± → e±νe)/Γ(K± → μ±νμ) has long been considered as an excellent test of lepton universality and the Standard Model (SM) description of weak interactions. It was realized recently that the suppression of the SM contribution might enhance the sensitivity to SUSY-induced effects to an experimentally accessible level. The NA62 experiment at the CERN SPS has collected over 105 K → e ν decays during a dedicated run in 2007, aiming at achieving 0.5 % precision. Experimental strategy, details of the analysis and the final result on a partial set of data will be described. The result RK = (2.487 ± 0.013) × 10−5 is in agreement with the Standard Model expectation.

Abstract

The Branching Ratio (BR) of the rare decay K+ → π+ν is predicted with a small error in the framework of the standard model (SM). The contribution of long distance terms is suppressed thanks to the GIM mechanism and the short distance dynamics is almost completely described by well measured semileptonic operators. The cleanness of the SM prediction together with the small BR (~ 10−10) makes this decay an interesting opportunity to describe the presence and the contribution of the new physics using relatively low energy processes. The NA62 experiment at CERN aims at measuring O(100) events in two years of data taking with 10% background. From an experimental point of view this measurement is very challenging because the weakness of the signal signature and the huge amount of background processes. In this paper the key points of the experiment will be described after a brief introduction on theoretical aspects and present results.

Abstract

The experiment NA62 at CERN collected a large sample of K? leptonic decays in order to perform precise test of lepton universality, by measuring the helicity suppressed ratio RK = ?(K? ? e??)/?(K? ? ???). The final result of the analysis based on 59,963 K+ ? e+? candidates (~ 40% of the total data set) is RK = (2.486 ? 0.013) ? 10?5 and consistent with the predictions of the Standard Model. The aim for the future program of the experiment is to measure the branching ratio of the ultra-rare decay K+ ? ?+?? with 10% precision.

Abstract

The NA62 experiment aims to measure the very rare kaon decay K+ → π+ν at the CERN SPS. The expected branching ratio has been recently estimated within the Standard Model to be (8.22 ± 0.84) × 10-11. From the experimental side, 7 events has been found by E787/949 experiments at BNL providing a measurement of the branching ratio of (1.73+1.15-1.05) × 10-10. The aim of NA62 is to collect ~100 events in two years of data taking with a 10% background. A description of the setup and the R&D program is presented.
