Abstract

Scikit-HEP is a community-driven and community-oriented project with the goal of providing an ecosystem for particle physics data analysis in Python. Scikit-HEP is a toolset of approximately twenty packages and a few "affiliated" packages. It expands the typical Python data analysis tools for particle physicists. Each package focuses on a particular topic, and interacts with other packages in the toolset, where appropriate. Most of the packages are easy to install in many environments; much work has been done this year to provide binary "wheels" on PyPI and conda-forge packages. The Scikit-HEP project has been gaining interest and momentum, by building a user and developer community engaging collaboration across experiments. Some of the packages are being used by other communities, including the astroparticle physics community. An overview of the overall project and toolset will be presented, as well as a vision for development and sustainability., Comment: 6 pages, 3 figures, Proceedings of the 24th International Conference on Computing in High Energy and Nuclear Physics (CHEP 2019), Adelaide, Australia, 4-8 November 2019

Abstract

We report new STAR measurements of the single-spin asymmetries $A_L$ for $W^+$ and $W^-$ bosons produced in polarized proton--proton collisions at $\sqrt{s}$ = 510 GeV as a function of the decay-positron and decay-electron pseudorapidity. The data were obtained in 2013 and correspond to an integrated luminosity of 250 pb$^{-1}$. The results are combined with previous results obtained with 86 pb$^{-1}$. A comparison with theoretical expectations based on polarized lepton-nucleon deep-inelastic scattering and prior polarized proton--proton data suggests a difference between the $\bar{u}$ and $\bar{d}$ quark helicity distributions for $0.05 < x < 0.25$. In addition, we report new results for the double-spin asymmetries $A_{LL}$ for $W^\pm$, as well as $A_L$ for $Z/\gamma^*$ production and subsequent decay into electron--positron pairs.

Abstract

We report a nonsaturating linear magnetoresistance in charge-compensated bilayer graphene in a temperature range from 1.5 to 150 K. The observed linear magnetoresistance disappears away from charge neutrality, ruling out the traditional explanation of the effect in terms of the classical random resistor network model. We show that experimental results qualitatively agree with a phenomenological two-fluid model taking into account electron-hole recombination and finite-size sample geometry. © 2016 American Physical Society.

Abstract

A primary goal of the high luminosity era at RHIC will be the study of heavy quark behavior in Quark Gluon Plasma. The integration of high precision silicon-based tracking in the form of the Heavy Flavor Tracker for the STAR Experiment should enable the reconstruction and identification of charmed hadron decays, working in concert with STAR’s Time Projection Chamber to determine momenta and displacement of decay daughters from the primary collision vertex. To reach the precision demands, the new detectors must be calibrated and sufficiently accounted in tracking to observe charmed hadrons with high signal-to-noise. In this paper we will review the STAR Collaboration’s developments and achievements in this critical effort.

Abstract

The electronic properties of bilayer graphene strongly depend on relative orientation of the two atomic lattices. Whereas Bernal-stacked graphene is most commonly studied, a rotational mismatch between layers opens up a whole new field of rich physics, especially at small interlayer twist. Here we report on magnetotransport measurements on twisted graphene bilayers, prepared by folding of single layers. These reveal a strong dependence on the twist angle, which can be estimated by means of sample geometry. At small rotation, superlattices with a wavelength in the order of 10 nm arise and are observed by friction atomic force microscopy. Magnetotransport measurements in this small-angle regime show the formation of satellite Landau fans. These are attributed to additional Dirac singularities in the band structure and discussed with respect to the wide range of interlayer coupling models., The properties of bilayer graphene can be tuned by twisting the layers relative to one another. Schmidt et al. now demonstrate the twist angle dependence of magnetotransport in this material system and uncover the formation of satellite Landau fans in the small-angle regime because of superlattice formation

Abstract

Aharonov-Bohm oscillations are observed in a graphene quantum ring with a top gate covering one arm of the ring. As graphene is a gapless semiconductor this geometry allows to study not only the quantum interference of electrons with electrons or holes with holes but also the unique situation of quantum interference between electrons and holes. The period and amplitude of the observed Aharonov-Bohm oscillations are independent of the sign of the applied gate voltage showing the equivalence between unipolar and dipolar interference., Comment: 4 pages, 3 figures

13. Measurement of the ratio of top-quark branching fractions top quark decaying to W boson and bottom quark and top quark decaying to W boson and any quark in the lepton + jets and dilepton channels at the Collider Detector at Fermilab

Abstract

According to the Standard Model, the top quark decays to a W boson and a b quark virtually 100% of the time. The measurements of tt¯ production cross section depend strongly on that assumption. We test this hypothesis with a measurement of R = B(t → W b)/B(t → Wq), using a combination of event kinematics and b- tagging techniques. The measurement is carried out using a data sample produced in pp¯ collisions at 1.96 TeV and collected at the Collider Detector at Fermilab between March 2002 and September 2003 with an integrated luminosity of ∼ 162 pb−1. The branching ratio R is determined from the relative tt¯ tagging rates making the measurement independent of any assumption on the tt¯ cross section. Any two tagging rates are sufficient to determine the R but the problem is overconstrained if more than two tagged subsamples are used. The tt¯ events are classified by the number vii of leptons in the final state. In lepton-plus-jets channel only one of the W bosons decays leptonically, whereas in dilepton channel both W bosons decay leptonically. The measurement of R is performed in both lepton-plus-jets and dilepton samples. In the lepton-plus-jets channel the background is estimated using the artificial neural network (ANN) technique. The ANN approach allows us to measure the signal fraction in samples with any number of tags. By applying this method alone the branching ratio was measured to be R = 1.06+0.27(stat.) ± 0.16(syst.). Alternatively, the tagged background contamination in lepton-plus-jets channel is determined from a traditional a priori method using data driven and Monte Carlo based techniques. A similar approach is used to determine the tt¯ content in the dilepton sample. The combination of ANN background measurement in lepton-plus- jets data sample with the a priori lepton-plus-jets and dilepton estimations leads to improved sensitivity in the final value of R = 1.12+0.21(stat.)+0.17(syst.). −0.19 −0.13 Finally, we construct the confidence level bands based on the method proposed by Feldman and Cousins. From these bands and our final measurement of R we set the lower limit of R > 0.61 at 95% confidence level.

Abstract

The influence of high magnetic fields on coherent transport is investigated. A monolayer graphene quantum ring is fabricated and the Aharonov-Bohm effect is observed. For increased magnitude of the magnetic field, higher harmonics appear. This phenomenon is attributed to an increase of the phase coherence length due to reduction of spin flip scattering. © 2014 AIP Publishing LLC.
