| Abstract | Top squark (stop) can be produced via QCD interaction but also the electro weak interaction at the LHC. In this paper, we investigate the observability of the associated production of stop and chargino, pp -> t(1)chi(-)(1), in compressed electroweakino scenarios at 14TeV LHC. Due to small mass splitting between the lightest neutralino (chi(0)(1)) and chargino (chi(-)(1)), the single stop production can give the mono-top signature through the stop decay t(1) -> t chi(0)(1). We analyze the leptonic mono-top channel of the single stop production and propose a lab-frame observable cos 0(bl) to reduce the SM backgrounds. We find that such leptonic mono-top events from the single stop production can be probed at 2 sigma level at the HL-LHC if m(t1) < 760 GeV and m(chi)(1)(0) < 150 GeV. Given a discovery of the stop and a measurement of the single stop production cross section, the stop mixing angle can also be determined from the single stop production at the HL-LHC. |
