 Scintillation properties and timing performance of state-of-the-art Gd$_{3}$Al$_{2}$Ga$_{3}$O$_{12}$single crystals / Martinazzoli, Loris (CERN ; Milan U.) ; Kratochwil, Nicolaus (CERN ; Vienna U.) ; Gundacker, Stefan (CERN ; Milan Bicocca U. ; RWTH Aachen U.) ; Auffray, Etiennette (CERN) Future colliders will set stringent requirements on the performance of detector materials in terms of timing and radiation hardness. Scintillating garnet crystals proved to satisfy the latter, while the former can be improved through technological developments. [...] 2021 - 7 p. - Published in : Nucl. Instrum. Methods Phys.

 Fully - heavy tetraquark production by $\gamma\gamma$ interactions in hadronic collisions at the LHC / Goncalves, Victor P. (Pelotas U.) ; Moreira, Bruno D. (UDESC, CCT) We investigate the production of the fully - heavy tetraquark states $T_{4Q}$ in the $\gamma \gamma$ interactions present in proton-proton, proton-nucleus and nucleus-nucleus collisions at the CERN Large Hadron Collider (LHC). We focus on the $\gamma \gamma \rightarrow {\cal{Q}}{\cal{Q}}$ (${\cal{Q}} = J/\psi,\, \Upsilon$) subprocess, mediated by the $T_{4Q}$ resonance in the $s$ - channel, and present predictions for the hadronic cross sections considering the kinematical ranges probed by the ALICE and LHCb Collaborations.

 Implementation of the ATLAS-EXOT-2018-030 analysis in the MadAnalysis 5 framework ($W′$ boson into a lepton and a neutrino; 139 fb$^{−1}$) / Park, Kyungmin (Seoul U.) ; Min, Ui (KAIST, Taejon) ; Lee, Soo Jin (Konkuk U.) ; Jun, Won (Seoul Natl. U. (main)) We present the MadAnalysis 5 implementation of the heavily charged gauge boson search to recast the analysis of its decay into one charged lepton and missing transverse momentum. Signal events describing pp → W′→ lν l (l = e or μ) at s = 13 TeV in the sequential standard model are generated by the MadGraph5_aMC@NLO at leading order. [...] 2020 - 10 p. - Published in : Mod.

 Search For Dark Matter produced in association With a Higgs Boson in the four lepton final state at 13 TeV With CMS Experiment / Aly, Reham (Bari U. ; INFN, Bari) /CMS Collaboration A search for dark matter (DM) particle produced in association with a Higgs Boson (H), where the Higgs boson decays to pair of Z bosons and each Z decays to two leptons ($e, \mu$) is presented. This is the first search for DM particles through this decay channel.

 Search for supersymmetric partners of third-generation quarks in 139 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector. / Pereira Sanchez, Laura (Stockholm U. (main) ; Stockholm U., OKC) /ATLAS Collaboration This poster presents the latest results on searches for pair production of supersymmetric partners of the top and bottom quarks using the LHC proton-proton collision data, recorded by the ATLAS detector at a centre of mass energy of $\sqrt{s} = 13$ TeV from 2015 to 2018, corresponding to an integrated luminosity of 139 fb$^{-1}$. Three main analyses are presented; a search for top squark pair production in events with $Z$ bosons, a search for bottom squark pair production in events with two Higgs bosons and a search for top squark pair production in events with a three body decay.
