Differential cross-section measurement of the tZq process with the ATLAS detector — •Nilima Akolkar and Ian Brock — Physikalisches Institut, Universität Bonn
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 a special interest, as it allows to probe the couplings of the Z-boson to the quark sector and W-boson simultaneously.
This talk will focus on the differential cross-section measurement of the tZq production, analyzed in the trilepton decay channel. The data used were collected with the ATLAS detector during Run 2 of the LHC, corresponding to an integrated luminosity of 139 fb−1. The differential cross-section is measured using unfolding and the preliminary results will be presented.
