Abstract

The projected reach of direct electroweakino searches at the high luminosity LHC (HL-LHC) (√(s)=14 TeV, 3000 fb^\ensuremath-1 LHC) in the framework of simplified models with R-parity violating operators, \ensuremathλ₁₁₂^\ensuremath'\ensuremath'u^cd^cs^c and \ensuremathλ₁₁₃^\ensuremath'\ensuremath'u^cd^cb^c, is studied. Four different analysis channels are chosen: Wh mediated 1l+2b+jets+)E_T, Wh mediated 1l+2\ensuremathγ+jets+)E_T, WZ mediated 3l+jets+)E_T and WZ mediated 3l+2b+jets+)E_T and the projected exclusion/discovery reach of direct wino searches in these channels is analyzed by performing a detailed cut-based collider analysis. The projected exclusion contour reaches up to 600--700 GeV for a massless binolike \ensuremathχ₁⁰ from searches in the Wh mediated 1l+2b+jets+)E_T, Wh mediated 1l+2\ensuremathγ+jets+)E_T and WZ mediated 3l+jets+)E_T channels, while the WZ mediated 3l+2b+jets+)E_T search channel is found to have a projected exclusion reach up to 600 GeV for 150 GeV<M_\ensuremathχ₁⁰<250 GeV. The baryon number violating simplified scenario considered in this work is found to furnish a weaker projected reach (typically by a factor of \ensuremath∼1/2) than the R-parity conserving (RPC) case. The projected reach at the HL-LHC in these four channels is also recast for realistic benchmark scenarios.
