abstract = {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’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 $t\bar{t}$ 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. The mistag rate
scale factors are estimated separately for events with low
and high average numbers of interactions per bunch crossing.
The results, which are derived from events with low missing
transverse momentum, are successfully validated in a phase
space characterized by high missing transverse momentum and
therefore are applicable to new physics searches carried out
in either phase space regime.},
