New ATLAS group publication

“Search for pair production of third-generation scalar leptoquarks decaying into a top quark and a τ-lepton in pp collisions at s√=13 TeV with the ATLAS detector” has been submitted to JHEP.
This paper presents the first dedicated ATLAS search for pair production of scalar leptoquarks with a significant branching ratio into a top quark and a tau lepton.
Scalar leptoquarks decaying exclusively into tτ are excluded up to masses of 1.43 TeV while, for a branching fraction of 50% into tτ, the lower mass limit is 1.22 TeV. These are the most stringent direct limits to date on such production and decay modes.
Members of the IFAE-ATLAS team have played a leading role in this publication. In particular, Stergios Kazakos is one of the main analyzers, and Aurelio Juste the corresponding editor for the paper.
