An analysis of 36.1 fb(-1) of root s = 13 TeV proton-proton collisions collected using the ATLAS detector at the LHC yields no significant excess over the expected Standard Model background. To interpret the results a simplified supersymmetric model is used where the top squark is assumed to decay via (t) over tilde (1) -> t((*)) (chi) over tilde (0)(1) and (t) over tilde (1) -> b (chi) over tilde (+/-)(1) -> bW((*)) (chi) over tilde (0)(1), where (chi) over tilde (0)(1) ((chi) over tilde (+/-)(1) denotes the lightest neutralino (chargino). Exclusion limits are placed in terms of the top-squark and neutralino masses. Assuming a branching ratio of 100{\%} to t (chi) over tilde (0)(1), top-squark masses in the range 450-1000 GeV are excluded for (chi) over tilde (0)(1) masses below 160 GeV. In the case where m((t) over tilde1) similar to m(t) + m((chi) over tilde 10), top-squark masses in the range 235-590 GeV are excluded.", optnote="WOS:000418558900001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3438), last updated on Wed, 10 Jan 2018 09:01:23 +0000", issn="1029-8479", doi="10.1007/JHEP12(2017)085", opturl="http://arxiv.org/abs/1709.04183", opturl="https://doi.org/10.1007/JHEP12(2017)085", archivePrefix="arXiv", eprint="1709.04183", language="English" }
