Searches for third-generation scalar leptoquarks in $$ \sqrt{s} $$ = 13 TeV pp collisions with the ATLAS detector
Description
<jats:title>A<jats:sc>bstract</jats:sc> </jats:title> <jats:p>Limits are set on the pair production of scalar leptoquarks, where all possible decays of the leptoquark into a quark (<jats:italic>t</jats:italic>, <jats:italic>b</jats:italic>) and a lepton (<jats:italic>τ</jats:italic>, <jats:italic>ν</jats:italic>) of the third generation are considered. The limits are presented as a function of the leptoquark mass and the branching ratio into charged leptons for up-type (LQ <jats:sub>3</jats:sub> <jats:sup>u</jats:sup> → <jats:italic>tν</jats:italic>/<jats:italic>bτ</jats:italic>) and down-type (LQ <jats:sub>3</jats:sub> <jats:sup>d</jats:sup> → <jats:italic>bν</jats:italic>/<jats:italic>tτ</jats:italic>) leptoquarks. Many results are reinterpretations of previously published ATLAS searches. In all cases, LHC proton-proton collision data at a centre-of-mass energy of <jats:inline-formula> <jats:alternatives> <jats:tex-math>$$ \sqrt{s} $$</jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> </mml:math> </jats:alternatives> </jats:inline-formula> = 13 TeV recorded by the ATLAS detector in 2015 and 2016 are used, corresponding to an integrated luminosity of 36.1 fb<jats:sup>−1</jats:sup>. Masses below 800 GeV are excluded for both LQ <jats:sub>3</jats:sub> <jats:sup>u</jats:sup> and LQ <jats:sub>3</jats:sub> <jats:sup>d</jats:sup> independently of the branching ratio, with masses below about 1 TeV being excluded for the limiting cases of branching ratios equal to zero or unity. </jats:p>
