Differential cross-section measurement of the tZq process with the ATLAS detector — •Nilima Akolkar1, Ian Brock1, Lidia Dell’Asta2, and Thomas Stevenson3 for the ATLAS collaboration — 1Physikalisches Institut, Universität Bonn — 2University of Milano — 3University of Sussex
The associated production of a single top-quark with a Z-boson (tZq) is a rare process that has been discovered by the CMS and ATLAS Collaborations. This process is of special interest, as it allows one to probe the couplings of the Z-boson to the quark sector and to the W-boson simultaneously.
This talk will focus on the differential cross-section measurement of the tZq process, analyzed in the trilepton decay channel. The data used was collected with the ATLAS detector during Run 2 of the LHC. The tZq differ- ential cross-section is measured using profile likelihood unfolding and the preliminary results will be presented in the talk.
