Title: | Searches for third-generation scalar leptoquarks in √s = 13 TeV pp collisions with the ATLAS detector | Authors: | Santos, S. P. Amor dos Fiolhais, M. C. N. Galhardo, B. Veloso, F. Wolters, H. ATLAS Collaboration |
Keywords: | Hadron-Hadron scattering (experiments) | Issue Date: | 2019 | Publisher: | Springer Nature | Serial title, monograph or event: | Journal of High Energy Physics | Volume: | 2019 | Issue: | 6 | Abstract: | Limits are set on the pair production of scalar leptoquarks, where all possible decays of the leptoquark into a quark (t, b) and a lepton (τ, ν) 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 (LQ3 u → tν/bτ) and down-type (LQ3 d → bν/tτ) 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 s = 13 TeV recorded by the ATLAS detector in 2015 and 2016 are used, corresponding to an integrated luminosity of 36.1 fb−1. Masses below 800 GeV are excluded for both LQ3 u and LQ3 d 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.[Figure not available: see fulltext.]. | URI: | https://hdl.handle.net/10316/107091 | DOI: | 10.1007/JHEP06(2019)144 | Rights: | openAccess |
