Global electroweak fit in the FCC-ee era / Erler, J (Mexico U. ; U. Mainz, PRISMA) ; Schott, M (U. Mainz, PRISMA)
The top quark and Higgs boson masses have been predicted before their respective discoveries by the global fit of the Standard Model to electroweak precision data. With the Higgs boson discovery and the measurement of its mass, the last missing parameter of the Standard Model has been fixed and thus the internal consistency of the Standard Model can be probed at a new level by comparing direct measurements with the indirect predictions of the global electroweak fit.

Optical properties and radiation hardness of Pr-doped Sol-Gel silica: influence of fiber drawing process / Fasoli, M. (University of Milano-Bicocca) ; Cova, F. (University of Milano-Bicocca) ; Moretti, F. (University of Milano-Bicocca) ; Chiodini, N. (University of Milano-Bicocca) ; Pauwels, K. (University of Milano-Bicocca) ; Auffray-Hillemanns, E. (CERN) ; Toliman Lucchini, M. (CERN) ; Bourret, E. (University of Milano) ; Veronese, I. (University of Milano, INFN Milano) ; d’Ippolito, E. (University of Milano) et al.
The optical emission from the 5d – 4f allowed transition of Pr3+ ions embedded in sol-gel silica is investigated for High Energy Physics applications requiring fast scintillating materials. A complete and detailed characterization of the optical, scintillation and radiation hardness properties of Pr-doped silica is carried out employing different experimental techniques including steady-state and time-resolved photo-luminescence, radio- and thermo-luminescence, scintillation and optical absorption. Optical absorption measurements, performed after X-ray irradiation sequences up to 1 kGy, evidence the formation of radiation-induced absorption bands related to point defects acting as color centers. Spontaneous partial recovery of the radiation-induced defects at room temperature, as well as after thermal treatments, is also disclosed. Particular attention is paid to the comparison between bulk silica, both before and after a melting process, and fibers. [...]

FPGA implementation of a histogram-based parent bunch-crossing identification for the Drift Tubes chambers of the CMS experiment / Pozzobon, Nicola (INFN, Padua ; Padua U.) ; Montecassiano, Fabio (INFN, Padua) ; Zotto, Pierluigi (U. Padua (main) ; INFN, Padua) /CMS Collaboration
The first running implementation on FPGA of a histogram-based trigger primitive generator for the CMS Drift Tubes at the High Luminosity LHC is presented. The foreseen architecture requires that raw charge collection times, measured for each tube by means of a TDC, are processed in the back-end to generate trigger primitives, identifying the parent bunch crossing and measuring the track parameters.

Upgrade of the ATLAS MDT Readout and Trigger for the HL-LHC / Richter, Robert (Munich, Max Planck Inst.) /ATLAS Collaboration
The luminosity increase at the LHC in Phase-II calls for an in-depth redesign of the MonitoredDrift Tube (MDT) chamber readout. One reason for this is the high rate of primary detectorsignals which requires increased readout bandwidth all along the data path. [...]

The CMS high granularity calorimeter for the high luminosity LHC / Valentan, Manfred (Vienna, OAW) /CMS Collaboration
The CMS (Compact Muon Solenoid) experiment at CERN will undergo significant improvements during the Phase-II Upgrade to cope with a 10-fold increase in integrated luminosity with the HL-LHC (High Luminosity Large Hadron Collider) era. The forward calorimetry faces very high radiation levels and pileup in the detectors. [...]

Linearity and saturation properties of Hamamatsu R5912-MOD photomultiplier tube for the ICARUS T600 light detection system / Babicz, Marta (CERN ; Cracow, INP) ; Bellini, Vincenzo (INFN, Catania ; Catania U.) ; Bonesini, Maurizio (INFN, Milan Bicocca) ; Cervi, Tommaso (INFN, Pavia ; Pavia U.) ; Falcone, Andrea (Texas U., Arlington (main)) ; Menegolli, Alessandro (INFN, Pavia ; Pavia U.) ; Montanari, Claudio (Pavia U. ; INFN, Pavia) ; Pietropaolo, Francesco (CERN) ; Raselli, Gian Luca (Pavia U. ; INFN, Pavia) ; Rossella, Massimo (INFN, Pavia ; Pavia U.) et al.
The ICARUS T600 liquid argon time projection chamber (LAr-TPC) will operate at shallow depth as far detector for the Short Baseline Neutrino (SBN) program at FNAL. A new scintillation light detection system, based on 360 Hamamatsu R5912-MOD Photomultiplier Tubes (PMTs), will allow to distinguish the actual beam related events from the huge cosmic background.

The Extreme Energy Events (EEE) experiment is a project by Centro Fermi (Museo Storico della Fisica e Centro Studi e Ricerche “Enrico Fermi”) in collaboration with INFN, CERN and MIUR, designed to study cosmic rays via a network of muon telescopes, based on the Multigap Resistive Plate Chambers (MRPC) technology. Due to its wide coverage over the Italian territory (more than 10° in latitude and longitude, covering more than 3x10$^5$ km$^2$), the EEE network is the largest MRPC – based system for cosmic rays detection.
