Abstract

“In the first part of my talk, I will review the recent work on the Exclusive pi-pi. This study is the measurement of the exclusive and semi-exclusive production of the charged pions at the LHC using the CMS detector. The dipion cross section and the differential cross section as a function of different kinematics are compared with the phenomenological predictions.

In second part, I will discuss the development of a timing detector which is based on fused silica (quartz) Cherenkov radiators readout with micro channel plate photomultipliers (MCP-PMTs) or silicon photomultiplier (SiPMs) for high precision timing (sigma_t = 10-15 ps).
