Experimental search potential for sbottom via ${\tilde{\chi }}_1^{\pm }$ decays at the LHC Run-3 and HL-LHC, in final states with same-sign leptons and multiple jets

Abstract

This paper explores the experimental search potential for sbottom pair production in an R-parity conserving scenario at the LHC Run-3 and HL-LHC. The sbottom decays with a 100% BR via a chargino, ${\tilde{b}}_1\to t{\tilde{\chi }}_1^{\pm }$, which subsequently decays to a $W$ boson and a neutralino, ${\tilde{\chi }}_1^{\pm }\to W{\tilde{\chi }}_1^0$, also with a 100% BR. The study follows the ATLAS object definitions and event selection criteria from Ref. JHEP06(2020)046, focusing on Rpc2L1b and Rpc2L2b signal regions defined with same-sign leptons and at least one $b$-tagged jet. Projected exclusion limits are presented in the ${\tilde{b}}_1$ - ${\tilde{\chi }}_1^0$ mass plane for three center-of-mass energies (13 TeV, 13.6 TeV, and 14 TeV) and three integrated luminosity scenarios (139 fb${}^{-1}$, 300 fb${}^{-1}$, and 3000 fb${}^{-1}$). keywords: sbottom pair production, same-sign leptons, multi-leptons
