abstract = {A technique is presented to measure the efficiency
with which c-jets are mistagged as b-jets (mistagging
efficiency) using t ¯t events, where one of theW 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 → cs branching ratio, which
allows ameasurement to be made in an inclusive c-jet sample.
The data sample used was collected by the ATLAS detector
at
√
s = 13 TeV and corresponds to an integrated luminosity
of 139 fb−1. Events are reconstructed using a kinematic
likelihood technique which selects the mapping between jets
and t ¯t 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. The total uncertainties are in the
range 3–17%. The measurements generally agree with those
in simulation but there are some differences in the region corresponding
to the most stringent b-jet tagging requirement.},
