Search for a leptoquark in events with a hadronically decaying τ-lepton and missing transverse momentum using pp collisions at s=13TeV with the ATLAS detector
Abstract
A search for leptoquark signals is performed in final states with a hadronically decaying τ -lepton and missing transverse momentum, using data from proton–proton collisions at a centre-of-mass energy of s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider during Run 2 (2015–18), corresponding to an integrated luminosity of 140 fb − 1 . The analysis is designed to probe both resonant production and non-resonant t -channel exchange of the leptoquark, covering a wide range of coupling scenarios. No excess above the Standard Model background prediction is observed. Limits are set on the couplings in the benchmark U 1 vector-leptoquark model at 95% confidence level for masses between 1.5 TeV and 3.0 TeV.
