Search for a right-handed W boson decaying to a heavy neutral lepton

The goal of the project is to look for the right-handed W (WR) boson and a heavy neutrino. Even though only left-handed W bosons are predicted by the Standard Model, there is no fundamental reason why right-handed W bosons should not exist, and many extensions to the Standard Model predict the existence of WR. For this project, we analyzed simulated data from the Compact Muon Solenoid (CMS) experiment to improve the event selection from the previous analysis done on Run2 data (collected from 2016-2018) in order to increase the sensitivity of the search for a WR boson. By applying high jet pT thresholds and b-tagging, we significantly improved the signal-background ratio, and the newly improved analysis will be used in the next version of the search (Run3).
