Calibration of a soft secondary vertex tagger using proton-proton collisions at SQUARE ROOTs=13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

Several processes studied by the ATLAS experiment at the Large Hadron Collider produce low momentum b-flavored hadrons in the final state. This paper describes the calibration of a dedicated tagging algorithm that identifies b-flavored hadrons outside of hadronic jets by reconstructing the soft secondary vertices originating from their decays. The calibration is based on a proton-proton collision dataset at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 140 fb-1. Scale factors used to correct the algorithm&apos;s performance in simulated events are extracted for the b-tagging efficiency and the mistag rate of the algorithm using a data sample enriched in t-t events. Several orthogonal measurement regions are defined, binned as a function of the multiplicities of soft secondary vertices and jets containing a b-flavored hadron in the event.
