 2018-02-0623:04 [PUBDB-2018-01083] Preprint/Report et al Halo-independent comparison of direct detection experiments in the effective theory of dark matter-nucleon interactions [DESY 18-015] The theoretical interpretation of dark matter direct detection experiments is hindered by uncertainties of the microphysics governing the dark matter-nucleon interaction, and of the dark matter density and velocity distribution inside the Solar System. These uncertainties are especially relevant when confronting a detection claim to the null results from other experiments, since seemingly conflicting experimental results may be reconciled when relaxing the assumptions about the form of the interaction and/or the velocity distribution.

The analysis uses data collected with the CMS detector at the CERN LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV.

This study is performed using proton-proton collisions at a center-of-mass energy of 13 TeV, in data recorded by the CMS detector in 2016 at the LHC, corresponding to an integrated luminosity of 36 fb$^{-1}$. [...] Restricted: PDF PDF (PDFA); 2018-02-0510:51 [PUBDB-2018-01039] Preprint/Report et al Comparing transverse momentum balance of b jet pairs in pp and PbPb collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeVC [CMS-HIN-16-005; CERN-EP-2018-005; arXiv:1802.00707; CMS-HIN-16-005; CERN-EP-2018-005] The transverse momentum balance of pairs of back-to-back b quark jets in PbPb and pp collisions recorded with the CMS detector at the LHC is reported. The center-of-mass energy in both collision systems is 5.02 TeV per nucleon pair. [...] Restricted: PDF PDF (PDFA); 2018-01-2610:58 [PUBDB-2018-00843] Preprint/Report Wang, K. Search for Singly Charged Higgs in Vector Boson Scattering at the ep Colliders [DESY-17-150; arXiv:1712.07505]   We search for a five-plet singly charged Higgs $H_5^\pm$ in the Georgi-Machacek model at the ep colliders. The charged Higgs bosons are produced via the $ZW^{\pm}$ fusion process $p\, e^- \to j\, e^-\, H_5^\pm$, and decay as $H_5^\pm \to Z\, W^{\pm} \to (l^+ l^-)\, (jj)$. [...] OpenAccess: PDF PDF (PDFA); 2018-01-2516:50 [PUBDB-2018-00842] Preprint/Report et al Control Software for the SST-1M Small-Size Telescope prototype for the Cherenkov Telescope Array [arXiv:1709.04244]   The SST-1M is a 4-m Davies--Cotton atmospheric Cherenkov telescope optimized to provide gamma-ray sensitivity above a few TeV. The SST-1M is proposed as part of the Small-Size Telescope array for the Cherenkov Telescope Array (CTA), the first prototype has already been deployed. [...] OpenAccess: PDF PDF (PDFA); 2018-01-2516:47 [PUBDB-2018-00841] Preprint/Report CTA Collaboration End-to-end data acquisition pipeline for the Cherenkov Telescope Array [arXiv:1709.04203]   The Cherenkov Telescope Array (CTA) will operate several types of telescopes and cameras. The individual camera trigger rates will vary much - from 0.6 to 15 kHz - while the content of the raw data will be heterogeneous. [...] OpenAccess: PDF PDF (PDFA); 2018-01-2516:42 [PUBDB-2018-00840] Preprint/Report et al Gammapy: high level data analysis for extragalactic science cases with the Cherenkov Telescope Arrayonsortium [arXiv:1709.10169]   The Cherenkov Telescope Array (CTA) observatory will probe the non-thermal universe above 20 GeV up to several hundreds of TeV with a significant improvement in sensitivity and angular resolution compared to current experiments. Its outstanding capabilities will allow to increase the number of extragalactic cosmic accelerators detected at very high energy (VHE) and therefore to better constrain the population of VHE accelerators and the gamma-ray absorption processes in the intergalactic medium. [...] OpenAccess: PDF PDF (PDFA); 2018-01-2516:38 [PUBDB-2018-00839] Preprint/Report et al Exploring deep learning as an event classification method for the Cherenkov Telescope Array [arXiv:1709.05889]   Telescopes based on the imaging atmospheric Cherenkov technique (IACTs) detect images of the atmospheric showers generated by gamma rays and cosmic rays as they are absorbed by the atmosphere. The much more frequent cosmic-ray events form the main background when looking for gamma-ray sources, and therefore IACT sensitivity is significantly driven by the capability to distinguish between these two types of events. [...] OpenAccess: PDF PDF (PDFA); 2018-01-2516:33 [PUBDB-2018-00838] Preprint/Report et al Studies of the nature of the low-energy, gamma-like background for Cherenkov Telescope Array [arXiv:1709.04245]   The upcoming Cherenkov Telescope Array (CTA) project is expected to provide unprecedented sensitivity in the low-energy ( <~100 GeV) range for Cherenkov telescopes. In order to exploit fully the potential of the telescopes the standard analysis methods for gamma/hadron separation might need to be revised. [...] OpenAccess: PDF PDF (PDFA);
