Electroweakino searches at the HL-LHC in the baryon number violating MSSM

Abstract

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