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 13 TeV.  No significant deviation from the expected Standard Model background is observed.  Limits are derived in scenarios of  direct production of stau pairs with each stau decaying into the stable lightest neutralino   and one $\\tau$-lepton in simplified models where the two stau mass eigenstates are degenerate.   Stau masses from 120 GeV to 390 GeV are excluded at  95% confidence level for a massless lightest neutralino.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t1","@type":"Dataset","description":"The observed upper limits on the model cross-section in units of pb for simplified models with combined ${\\tilde{\\tau}}^{+}_{R,L} {\\tilde{\\tau}}^{-}_{R,L}$ production....","name":"X-section U.L 1"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t2","@type":"Dataset","description":"The observed upper limits on the model cross-section in units of pb for simplified models with ${\\tilde{\\tau}}_L {\\tilde{\\tau}}_L$ only production....","name":"X-section U.L 2"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t3","@type":"Dataset","description":"The observed 95\\% CL exclusion contours for the combined fit of SR-lowMass and SR-highMass for simplified models with combined ${\\tilde{\\tau}}^{+}_{R,L}...","name":"Exclusion contour 1 (Obs.)"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t4","@type":"Dataset","description":"The expected 95% CL exclusion contours for the combined fit of SR-lowMass and SR-highMass for simplified models with combined ${\\tilde{\\tau}}^{+}_{R,L}...","name":"Exclusion contour 1 (Exp.)"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t5","@type":"Dataset","description":"The observed 95% CL exclusion contours for the combined fit of SR-lowMass and SR-highMass for simplified models with ${\\tilde{\\tau}}_L {\\tilde{\\tau}}_L$...","name":"Exclusion contour 2 (Obs.)"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t6","@type":"Dataset","description":"The expected 95% CL exclusion contours for the combined fit of SR-lowMass and SR-highMass for simplified models with ${\\tilde{\\tau}}_L {\\tilde{\\tau}}_L$...","name":"Exclusion contour 2 (Exp.)"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t7","@type":"Dataset","description":"Observed 95% CL exclusion limits for simplified models with direct stau pair production in SR-lowMass.","name":"Exclusion contour aux 1 (Obs.)"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t8","@type":"Dataset","description":"Expected 95% CL exclusion limits for simplified models with direct stau pair production in SR-lowMass.","name":"Exclusion contour aux 1 (Exp.)"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t9","@type":"Dataset","description":"Observed 95% CL exclusion limits for simplified models with direct stau pair production in SR-highMass.","name":"Exclusion contour aux 2 (Obs.)"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t10","@type":"Dataset","description":"Expected 95% CL exclusion limits for simplified models with direct stau pair production in SR-highMass.","name":"Exclusion contour aux 2 (Exp.)"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t11","@type":"Dataset","description":"Signal acceptance in SR highMass for combined stau final states","name":"Acc_table_SRhigh"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t12","@type":"Dataset","description":"Signal acceptance in SR lowMass for combined stau final states","name":"Acc_table_SRlow"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t13","@type":"Dataset","description":"Signal efficiency in SR highMass for combined stau final states","name":"Eff_table_SRhigh"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t14","@type":"Dataset","description":"Signal efficiency in SR lowMass for combined stau final states","name":"Eff_table_SRlow"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t15","@type":"Dataset","description":"Signal acceptance*efficiency in SR highMass for combined stau final states","name":"Eff_Acc_table_SRhigh"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t16","@type":"Dataset","description":"Signal acceptance*efficiency in SR lowMass for combined stau final states","name":"Eff_Acc_table_SRlow"},{"@id":"https://doi.org/10.17182/hepdata.92006.v2/t17","@type":"Dataset","description":"Cutflow for two reference points (${\\tilde{\\tau}}^{+}_{R,L} {\\tilde{\\tau}}^{-}_{R,L}$ production) in SR.
