In view of the High Luminosity upgrade CERN LHC, forward CMS Muon spectrometer will be extended with two new stations improved Resistive Plate Chambers (iRPC) covering pseudorapidity range from 1.8 to 2.4. Compared present RPC system, gap thickness is reduced lower avalanche charge, and an innovative 2D strip readout geometry proposed. These improvements allow iRPC detector cope higher background rates. A Front-End-Board (FEB) designed signals a threshold as low 30 fC integrated Time Digital...

In this paper, a study of four different machine learning (ML) algorithms is performed to determine the most suitable ML technique disentangle hypothetical supersymmetry (SUSY) signal from its corresponding Standard Model (SM) backgrounds and establish their impact on significance. The focuses production SUSY top squark pairs (stops), in mass range [Formula: see text][Formula: text]GeV, proton–proton collisions with center energy 13[Formula: text]TeV an integrated luminosity text], emulating...

For two years (Spring 2013 - Spring 2015), the LHC went through its first long shutdown (LS1). It was mainly motivated by consolidation of magnet interconnects, to allow operation with 6.5 TeV proton beams. Moreover, around accelerator complex, many other systems were repaired, consolidated or upgraded, and several new installations came life. The standardization vacuum controls has progressed in injectors, renovation most their obsolete equipment. In LHC, instruments added, signal...
