Performance of the CMS 2S $p_T$ module prototype using CBC2 readout at beam tests / Roy Chowdhury, Suvankar (Saha Inst.) /CMS Collaboration
As the LHC will enter into its high luminosity phase\,(HL-LHC), operating at a luminosity of $5\rm{\mbox{-}}7.5\times10^{34}~\rm cm^{-2}\rm s^{-1}$, the CMS experiment will replace the Run 2 tracker with a new one which will be able to sustain the increased number of collisions per bunch crossing, which can be as high as 200. The tracker information will be used in the Level-1 trigger to reject low $p_T$ tracks. [...]

Large Extra Dimensions search in the photon + MET final state in pp Collisions at sqrt(s) = 13 TeV at CMS in LHC / Ghosh, Shamik (Saha Inst.) /CMS Collaboration
Techniques and results for searching graviton production predicted by the ADD large extra dimensions model in a final state with a photon and missing transverse energy in pp collisions at sqrt(s) = 13 TeV is presented. Data collected by the CMS experiment at the CERN LHC in 2016 corresponding to an integrated luminosity of 12.9 fb-1 is used for the analysis. [...]

Feasibility study of $B_s \rightarrow \phi \phi \rightarrow$ 4K with L1 Tracks at the CMS Phase-II Detector / Bhattacharya, Rajarshi (Saha Inst.) /CMS Collaboration
$B_s \rightarrow \phi \phi \rightarrow$ 4 Kaons is an important physics process to study during the LHC Phase-II which is expected to start in 2024. In this process, the CP violating weak phase arises due to the CP violation of the $B_s - \bar{B_s}$ mixing and the gluonic penguin decay of b $\rightarrow$ s$\bar s$s. [...]

The CMS Beam Halo Monitor at LHC implementation and first measurements / Tosi, Nicolo (INFN, Bologna ; Bologna U.) /CMS Collaboration
A Cherenkov based detector system has been installed at the Large Hadron Collider (LHC), in order to measure the Machine Induced Background (MIB) for the Compact Muon Solenoid (CMS) experiment.The system is composed of forty identical detector units formed by a cylindrical Quartz radiator directly coupled to a Photomultiplier. These units are installed at a radius of 1.8m and a distance of 20.6 m from the CMS interaction point.The fast and direction-sensitive signal allows to measure incoming MIB particles while suppressing the much more abundant collision products and albedo particles, which reach the detector at a different time and from a different direction.The system readout electronics is based on the QIE10 ASIC and a uTCA based back-end, and it allows a continuous online measurement of the background rate separately per each bunch.The detector has been installed in 2015 and is now fully commissioned.
