 Search for dark matter produced in association with a $Z$ boson in the ATLAS detector at the Large Hadron Collider / McLean, Kayla (University of Victoria) This dissertation presents a search for dark matter particles produced in association with a $Z$ boson in proton-proton collisions. The dataset consists of 139 fb$^{-1}$ of collision events with centre-of-mass energy of 13 TeV, and was collected by the ATLAS detector from 2015-2018 at the Large Hadron Collider.

 A fiber optic sensors monitoring system for the central beam pipe of the CMS experiment / Fienga, Francesco (CERN ; U. Naples (main) ; INFN, Naples) ; Szillasi, Zoltan (Debrecen, Inst. Nucl. Res.) ; Beni, Noemi (CERN) ; Irace, Andrea (Naples U.) ; Gaddi, Andrea (CERN) ; Zeuner, Wolfram (CERN) ; Ball, Austin (CERN) ; Buontempo, Salvatore (CERN ; INFN, Naples) ; Breglio, Giovanni (CERN ; U. Naples (main) ; INFN, Naples) In this paper we describe the main characteristics and experimental results, recorded in more than four years of data acquisition, of a temperature and strain monitoring system, called i-pipe, based on Fiber Bragg Grating (FBG) sensors arrays applied for the first time to a sector of the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN): the central beam pipe (BP) of the Compact Muon Solenoid (CMS). The monitoring system, consisting of four arrays of 16 FBG sensors each, as better described in the text, is placed on four directives of the LHC section that passes inside the CMS experiment, namely the CMS central BP.

 Study of a large size double stack MRPC with strip readout / Baek, Y W (CERN ; Gangneung-Wonju Natl. U.) ; Kim, D W (Gangneung-Wonju Natl. U.) ; Williams, M C S (CERN ; Gangneung-Wonju Natl. U. ; INFN, Bologna) The Multigap Resistive Plate Chambers (MRPC) have been using in many experiments for the purpose of particle identification by the measurement of time-of-flight, thanks to its excellent timing performance. We present here a new design of a large size MRPC. [...] 2019 - 4 p. - Published in : Nucl. Instrum. Methods Phys. Res., A 928 (2019) 89-92

 Low-complexity voltage and current sources for large-scale quench detection of high-temperature superconducting cables / Arpaia, P (CERN ; U. Naples (main)) ; Baccigalupi, C (CERN ; U. Naples (main)) ; Esposito, A (CERN ; Turin Polytechnic ; U. Naples (main)) In this work, the design of precision voltage and current sources for a new quench detection system for theprotection of superconducting power cables is proposed. The key strength of the design resides in its lowcomplexity, which allows to obtain a low-cost and reliable hardware implementation for the new detector. [...] 2019 - 8 p. - Published in : Nucl.

 High-energy collisions of hadrons: what are the dynamical mechanisms? / Van Hove, L (CERN) A survey is given of the two dominant mechanisms which have been recognized to operate in high-energy collisions of hadrons, namely diffraction scattering and reggeized article exchange. The main characteristics of these mechanisms are discussed on the basis of the experimental evidence from two-body processes.
