This paper presents a measurement of the production cross-section of a Z boson in association with b-jets, in proton–proton collisions at √ s = 13 TeV with the ATLAS experiment at the Large Hadron Collider using data corresponding to an integrated luminosity of 35.6 fb−1. Inclusive and differential cross-sections are measured for events containing a Z boson decaying into electrons or muons and produced in association with at least one or at least two b-jets with transverse momentum pT > 20 GeV… Expand

Measurement of the $c$-jet mistagging efficiency in $t\bar{t}$ events using $pp$ collision data at $\sqrt{s}=13$ TeV collected with the ATLAS detector
A technique is presented to measure the efficiency with which c-jets are mistagged as b-jets (mistagging efficiency) using tt events, where one of theW bosons decays into an electron or muon and aExpand
