Description
Accurate identification of jets originating from b quarks has been of prime importance for many measurements and searches in CMS. The development of a charm tagger, a tool to identify jets initiated by charm quarks, will be no different, allowing analysts to broaden the spectra of their research. We detail the technique that was used to train an MVA–based discriminator to tag charm jets, its expected performance on simulations, and finally its calibration on top quark pairs. The datasets used for the calibration of the algorithm have been selected starting from the proton–proton collisions at the center–of–mass energy of √s= 13 TeV recorded by the CMS experiment during the start of LHC Run II in 2015.
