 100 milliards de rayons cosmiques détectés dans l’expérience AMS-02 / Aupetit, Sandy (LPSC, Grenoble) ; Maurin, David (LPSC, Grenoble) ; Poireau, Vincent (Annecy, LAPP) Notre planète est bombardée en permanence par le rayonnement cosmique, un ensemble de particules en provenance de l’espace. Orbitant à 400 km au-dessus de la Terre depuis la station spatiale internationale, l’expérience AMS-02 a déjà détecté plus de 100 milliards de particules depuis son installation, le 19 mai 2011.

 Energy calibration of the GEMPix in the energy range of 6 keV to 2 MeV / Leidner, J (CERN) ; Murtas, F (CERN ; LNF, Dafne Light) ; Silari, M (CERN) The GEMPix is a small gaseous detector with a highly pixelated readout, consisting of a drift region, three Gas Electron Multipliers (GEMs) for signal amplification, and four Timepix ASICs with 55 μm pixel pitch and a total of 262,144 pixels (512×512 pixels). A continuous flow of a gas mixture (here propane-based tissue equivalent gas) is supplied externally at a rate of 5 L/h. [...] 2021 - 11 p. - Published in : JINST 16 (2021) P10004 Fulltext: PDF;

 Latest single top differential cross section measurements at CMS / Rodríguez Bouza, Victor  (ICTEA, Oviedo) /CMS Collaboration Single top quark production is the subleading production process of top quarks at the LHC after the top quark pair production. The latest differential measurements of single top quark production cross sections are presented using data collected by the CMS detector at a center-of-mass energy of 13 TeV.

 Noble liquid calorimetry at the LHC and prospects of its application in future collider experiments / Aleksa, Martin (CERN) Calorimetry is an important measurement technique in experimental particle physics. Although calorimeters based on liquefied noble gases were first proposed 50 years ago, they continue to play an important role in modern particle physics and have substantially contributed to the discovery of the Higgs boson at the Large Hadron Collider (LHC) at CERN in 2012.. 2021 - 4 p. - Published in : Europhys.

 Type II seesaw mechanism with scalar dark matter in light of AMS-02, DAMPE, and Fermi-LAT data / Li, Tong (Monash U.) ; Okada, Nobuchika (Alabama U.) ; Shafi, Qaisar (Delaware U., Bartol Inst.) The Standard Model (SM) supplemented by Type II Seesaw and a SM gauge-singlet scalar dark matter (DM) is a very simple framework to incorporate the observed neutrino oscillations and provide a plausible DM candidate. In this framework, the scalar DM naturally has a leptophilic nature with a pair annihilating mainly into the SM SU(2)$_L$ triplet Higgs scalar of Type II Seesaw which, in turn, decay into leptons.

 A Precision Search for WIMPs with Charged Cosmic Rays / Reinert, Annika (Bonn U. ; U. Bonn, Phys. Inst., BCTP) ; Winkler, Martin Wolfgang (Nordita ; Royal Inst. Tech., Stockholm) AMS-02 has reached the sensitivity to probe canonical thermal WIMPs by their annihilation into antiprotons. Due to the high precision of the data, uncertainties in the astrophysical background have become the most limiting factor for indirect dark matter detection.

 WZ production in leptonic decays at CMS / Álvarez González, Bárbara  (ICTEA, Oviedo) /CMS Collaboration The study of the associated production of W and Z bosons is performed in proton-proton collisions using data collected by the CMS experiment. WZ production is one of the dominant multiboson production processes at the LHC energies.

 A thermal neutron source for the CERN radiation Calibration Laboratory / Ferrulli, Francesca (U. Caen (main) ; CERN) ; Silari, Marco (CERN) ; Thomsen, Frederik (CERN ; Aarhus U. (main)) ; Zorloni, Gabriele This work presents the design, construction and experimental characterisation of a lightweight and low-cost thermal neutron assembly, to be used with the existing Am–Be source irradiator of CERN radiation Calibration Laboratory (Cal Lab). The assembly consists of a cylindrical moderator (18 cm diameter, 25.5 cm height and 5.5 kg weight) and an optional reflector box (5 cm thick walls, 20 kg weight) [...] 2021 - 8 p. - Published in : Appl.

 Measurements of $CP$ violation in charmless 2-body $B$ meson decays at LHCb / Fazzini, Davide (INFN, Milan Bicocca ; Milan U.) /LHCb Collaboration Charmless charged two-body b-hadron decays, with kaons and pions in the final state, are an optimal test of the Standard Model validity. Indeed these decays receive important contributions from loop-level processes making the $C\!P$ asymmetries sensitive to transitions beyond the Standard Model.
