ALICE is a high-energy physics experiment at the CERN Large Hadron Collider (LHC) in Geneva, to study the properties of quark-gluon plasma, formed in heavy-ion collisions. In the upgrade program, a new electromagnetic forward calorimeter (FOCAL) based on silicon and tungsten (Si$+$W) sampling configuration, has been proposed to address new physics objectives of ALICE experiment.

Measurement of Electrons from Beauty-Hadron Decays in pp Collisions from $\sqrt{s}$ = 2.76 TeV to 13 TeV with ALICE
/ Singh, Vivek Kumar (Calcutta, VECC ; HBNI, Mumbai)
/ALICE Collaboration
In proton–proton collisions, measurements of beauty-hadron production cross sections are an effective tool to test perturbative QCD (pQCD) calculations. In addition, they provide the required reference for measurements performed in Pb–Pb and p–Pb collision systems, in order to study the in-medium mass-dependent partonic energy loss and the possible effects of cold nuclear matter, respectively.

Large area Gas Electron Multiplier (GEM) detectors have been the preferred choice for tracking devices in major nuclear and particle physics experiments. Uniformity over surface of the detector in terms of gain, energy resolution and efficiency is crucial for the optimum performance of these detectors. [...]
