Measurement of the c-jet mistagging efficiency in tt¯ events using pp collision data at √s = 13 TeV collected with the ATLAS detector
Popis výsledku v původním jazyce
A technique is presented to measure the efficiency with which c-jets are mistagged as b-jets (mistagging efficiency) using ttˉttˉ events, where one of the W bosons decays into an electron or muon and a neutrino and the other decays into a quark–antiquark pair. The measurement utilises the relatively large and known W→csW→cs branching ratio, which allows a measurement to be made in an inclusive c-jet sample. The data sample used was collected by the ATLAS detector at s=13s =13 TeVTeV and corresponds to an integrated luminosity of 139 fb−1−1. Events are reconstructed using a kinematic likelihood technique which selects the mapping between jets and ttˉttˉ decay products that yields the highest likelihood value. The distribution of the b-tagging discriminant for jets from the hadronic W decays in data is compared with that in simulation to extract the mistagging efficiency as a function of jet transverse momentum.
