| contents | 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, $\tilde{b}_1 \to t \tildeχ_1^\pm$, which subsequently decays to a $W$ boson and a neutralino, $\tildeχ_1^\pm \to W \tildeχ_1^0$, 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 $\tilde{b}_1$ - $\tildeχ_1^0$ 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$^{-1}$).
