The discovery of the Higgs boson in 2012, by ATLAS and CMS experiments, was a success achieved with only percent entire dataset foreseen for LHC. It opened landscape possibilities study properties, Electroweak Symmetry breaking Standard Model general, as well new avenues probing physics beyond Model. Six years after discovery, conspicuously larger collected during LHC Run 2 at 13 TeV centre-of-mass energy, theory experimental particle communities have started meticulous exploration potential...

Gas Electron Multipliers (GEM) are a proven position sensitive gas detector technology which nowadays is becoming more widely used in High Energy Physics. GEMs offer an excellent spatial resolution and high particle rate capability, with close to 100% detection efficiency. In view of the luminosity phase CERN Large Hadron Collider, these aforementioned features make suitable candidates for future upgrades Compact Muon Solenoid (CMS) detector. particular, CMS GEM Collaboration proposes cover...

Since muons constitute major background for neutrino interactions, muon flux entering acceptance also measured. To improve rejection power of detector increase fiducial volume, a third Veto plane recently installed. The energy resolution calorimeter system measured test beam. This will help with identification...
