Study of Physics Performances at Muon Collider / Bartosik, Nazar (INFN, Turin) ; Pastrone, Nadia (INFN, Turin) ; Bertolin, Alessandro (INFN, Padua) ; Gianelle, Alessio (INFN, Padua) ; Sestini, Lorenzo (INFN, Padua) ; Casarsa, Massimo (INFN, Trieste) ; Collamati, Francesco (INFN, Rome) ; Ferrari, Alfredo (CERN) ; Ferrari, Anna (Forschungszentrum Dresden Rossendorf) ; Lucchesi, Donatella (Padua U. ; INFN, Pavia) et al.
Muon Collider is a promising option for the next generation high-energy collider, possessing very low radiation losses due to synchrotron radiation.Treatment of the beam-induced background is one of the most critical issues in such a machine.Since the muon beams must be very intense to reach high luminosity, the muons decay products and subsequent particles from secondary interactions with the environment can reach the interaction point, limiting the physical performance of the detector.This talk presents a reconstruction strategy for a benchmark process, H->bb-bar, in the presence of the beam-induced background..

A Generative-Adversarial Network Approach for the Simulation of QCD Dijet Events at the LHC / Di Sipio, Riccardo (Toronto U.) ; Faucci Giannelli, Michele (Edinburgh U.) ; Ketabchi Haghighat, Sana (Toronto U.) ; Palazzo, Serena (Edinburgh U.)
A Generative-Adversarial Network (GAN) based on convolutional neural networks is used to simulate the production of pairs of jets at the LHC. The GAN is trained on events generated using MadGraph5, Pythia8, and Delphes3 fast detector simulation. [...]

Searches for charginos and neutralinos in ATLAS / Longo, Luigi (CERN) /ATLAS Collaboration
Supersymmetry (SUSY) is one of the most interesting theories describing physics beyond the Standard Model. An extensive program of SUSY searches has been consequently performed by the ATLAS experiment with the LHC data collected during Run-2. [...]

Status and prospects of simplified template cross sections measurements in ATLAS and CMS / Kato, Chikuma (Tsung-Dao Lee Inst., Shanghai) /ATLAS Collaboration ; CMS Collaboration
The Higgs boson production cross sections in exclusive kinematic bins are measured as simplified template cross sections (STXS), which are designed to reduce model dependence and maximize sensitivity to new physics beyond the Standard Model. This review summarizes the STXS results in the combined measurements in ATLAS and CMS experiments. [...]

The Tracker Endcap Pixel detector for CMS phase II upgrade / Del Burgo, Riccardo (Zurich U.) /CMS Collaboration
After the high-luminosity upgrade of the LHC (HL-LHC), the instantaneous luminosity will increase to unprecedented values of $5-7 \times10^{34}\,\mathrm{cm^{-2}s^{-1}}$. In order to cope with these conditions the whole CMS silicon tracker detector will be replaced. [...]

Reconstruction and identification of high-pT muons in $\sqrt{s}$ = 13 TeV proton-proton collisions with the ATLAS detector / Vannicola, Damiano (Rome U. ; INFN, Rome) /ATLAS Collaboration
The ability to reconstruct high-momentum muon tracks in ATLAS with good momentum resolution is closely connected to a good understanding of the ATLAS tracking detectors alignment and of the related uncertainties. Moreover, an optimal selection of muon candidates with transverse momentum of the order of TeVs is a critical factor in the sensitivity of analyses looking for new high-mass resonances, such as Z' ->μμ and W' -> μν searches.

Projections for HH measurements in the bbZZ(4l) final state with the CMS experiment at the HL-LHC / Fontanesi, Elisa (Bologna U. ; INFN, Bologna) ; Borgonovi, Lisa (Bologna U. ; INFN, Bologna)
Prospects for the study of Higgs boson pair (HH) production in the $\mathrm{HH \to b\bar{b}4l}$ (l = e, $\mu$) channel are studied in the context of the High Luminosity LHC. The analysis is performed using a parametric simulation of the Phase-2 CMS detector response provided by the Delphes software and assuming an average of 200 proton-proton collisions per bunch crossing at a center-of-mass energy of 14 TeV.

Time resolution of thin Low Gain Avalanche Detectors / Del Burgo, Riccardo (Zurich U.)
The CMS MIP Timing Detector, proposed for the HL-LHC upgrade, will be instrumented with O(10) square meters of ultra-fast Silicon detectors (UFSD) in the forward region. These UFSDs are aimed at measuring the time of passage of each track with a precision of about 30 ps. [...]
