Abstract |
Three searches for the direct production of tau-sleptons or charginos and neutralinos in final states with at least two hadronically decaying tau-leptons are presented. For chargino and neutralino production, decays via intermediate tau-sleptons or W and h bosons are considered. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of 139 fb(-1), recorded with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 13TeV. No significant deviation from the expected Standard Model background is observed and supersymmetric particle mass limits at 95% confidence level are obtained in simplified models. For direct production of (X) over tilde +/-(1) (X) over tilde -1, chargino masses are excluded up to 970 GeV, while (X) over tilde +/-(1) 1 and (X) over tilde (0)2 masses up to 1160 GeV (330 GeV) are excluded for (X) over tildeC(+/-) (1) (X) over tilde (0)(2) /(X) over tilde (+)(1) (X) over tilde -1 production with subsequent decays via t -sleptons ( W and h bosons). Masses of tau-sleptons up to 500 GeV are excluded for mass degenerate (tau) over tildeL, R scenarios and up to 425 GeV for (tau) over tilde (L) -only scenarios. Sensitivity to (tau) over tilde (R) -only scenarios from the ATLAS experiment is presented here for the first time, with (tau) over tilde (R) masses excluded up to 350 GeV. |
