Search for long-lived multiply-charged massive particles in pp collision at 13 TeV with the CMS detector

Some of the beyond the standard model (BSM) physics models predict the existence of massive particles with electric charge |Q|=ne, where n ∈ {2,3,4,...}. The poster outlines ongoing efforts to discover these multiply-charged massive particles (mCHAMPs) with lifetimes long enough to traverse the CMS detector, using Run2 data for proton-proton collisions at √s = 13 TeV. The study focuses on the identification of mCHAMPs through a distinctive detector response and employs a novel approach of using a High-Level Trigger (HLT) based candidate selection that varies over the charge space. This approach increases charge range that can be probed significantly compared to previous CMS results.
