Abstract

The projected reach of direct electroweakino searches at the HL-LHC (s=14 TeV, 3000 fb1\sqrt{s}=14~{\rm TeV}, ~3000~{\rm fb^{-1}} LHC) in the framework of simplified models with R-parity violating (RPV) operators: λ112ucdcsc\lambda_{112}^{\prime \prime}u^{c}d^{c}s^{c} and λ113ucdcbc\lambda_{113}^{\prime\prime}u^{c}d^{c}b^{c}, is studied. Four different analysis channels are chosen: WhWh mediated 1l+2b+jets+E ⁣ ⁣ ⁣/T1l+2b+jets+\rm E{\!\!\!/}_T, WhWh mediated 1l+2γ+jets+E ⁣ ⁣ ⁣/T1l+2\gamma+jets+\rm E{\!\!\!/}_T, WZWZ mediated 3l+jets+E ⁣ ⁣ ⁣/T3l+jets+\rm E{\!\!\!/}_T and WZWZ mediated 3l+2b+jets+E ⁣ ⁣ ⁣/T3l+2b+jets+\rm 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 600700 GeV600-700~{\rm GeV} for a massless bino-like χ10\chi_{1}^{0} from searches in the WhWh mediated 1l+2b+jets+E ⁣ ⁣ ⁣/T1l+2b+jets+\rm E{\!\!\!/}_T, WhWh mediated 1l+2γ+jets+E ⁣ ⁣ ⁣/T1l+2\gamma +jets+\rm E{\!\!\!/}_T and WZWZ mediated 3l+jets+E ⁣ ⁣ ⁣/T3l+jets+\rm E{\!\!\!/}_T channels, while the WZWZ mediated 3l+2b+jets+E ⁣ ⁣ ⁣/T3l+2b+jets+\rm E{\!\!\!/}_T search channel is found to have a projected exclusion reach up to 600 GeV600~{\rm GeV} for 150 GeV<Mχ10<250 GeV150~{\rm GeV} < M_{\chi_{1}^{0}} < 250~{\rm GeV}. The baryon number violating simplified scenario considered in this work is found to furnish a weaker projected reach (typically by a factor of 1/2\sim 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.
