A measurement of the high-mass $τ\barτ$ production cross-section at $\sqrt{s}=13$ TeV with the ATLAS detector and constraints on new particles and couplings
The production cross-section of high-mass $\tau$-lepton pairs is measured as a function of the dilepton visible invariant mass,
using 140 fb$^{-1}$ of $\sqrt{s}=13$ TeV proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider.
The measurement agrees with the predictions of the Standard Model. A fit to the invariant mass distribution is performed as a function
of b-jet multiplicity, to constrain the non-resonant production of new particles described by an effective field theory or in models
containing leptoquarks or $Z^\prime$ bosons that couple preferentially to third-generation fermions. The constraints on new particles
improve on previous results, and the constraints on effective operators include those affecting the anomalous magnetic moment of the
$\tau$-lepton.
