The results of a search for the stop, the supersymmetric partner of the top quark, in final states with one isolated electron or muon, jets, and missing transverse momentum are reported. The search uses the 2015 LHC $pp$ collision data at a center-of-mass energy of $\\sqrt{s}=13$ TeV recorded by the ATLAS detector and corresponding to an integrated luminosity of 3.2 fb${}^{-1}$. The analysis targets two types of signal models: gluino-mediated pair production of stops with a nearly mass-degenerate stop and neutralino; and direct pair production of stops, decaying to the top quark and the lightest neutralino. The experimental signature in both signal scenarios is similar to that of a top quark pair produced in association with large missing transverse momentum. No significant excess over the Standard Model background prediction is observed, and exclusion limits on gluino and stop masses are set at 95% confidence level. The results extend the LHC Run-1 exclusion limit on the gluino mass up to 1460 GeV in the gluino-mediated scenario in the high gluino and low stop mass region, and add an excluded stop mass region from 745 to 780 GeV for the direct stop model with a massless lightest neutralino. The results are also reinterpreted to set exclusion limits in a model of vector-like top quarks.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.74125.v1/t1","@type":"Dataset","description":"Comparison of data with estimated backgrounds in the $am_\\text{T2}$ distribution with the STCR1 event selection except for the requirement on...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.74125.v1/t2","@type":"Dataset","description":"Comparison of data with estimated backgrounds in the $b$-tagged jet multiplicity with the STCR1 event selection except for the requirement...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.74125.v1/t3","@type":"Dataset","description":"Comparison of data with estimated backgrounds in the $\\Delta R(b_1,b_2)$ distribution with the STCR1 event selection except for the requirement...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.74125.v1/t4","@type":"Dataset","description":"Comparison of data with estimated backgrounds in the $\\tilde{E}_\\text{T}^\\text{miss}$ distribution with the TZCR1 event selection except for the requirement on...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.74125.v1/t5","@type":"Dataset","description":"Comparison of data with estimated backgrounds in the $\\tilde{m}_\\text{T}$ distribution with the TZCR1 event selection except for the requirement on...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.74125.v1/t6","@type":"Dataset","description":"Comparison of the observed data ($n_\\text{obs}$) with the predicted background ($n_\\text{exp}$) in the validation and signal regions.
