Description
Supersymmetric models with radiatively-driven naturalness enjoy modest electroweak fine-tuning at the 10% level while respecting LHC sparticle and Higgs mass constraints. These models have an inverted electroweakino spectrum with $\mu < M_{1} < M_{2} < M_{3}$ leading to a rather clean same-sign diboson signature from wino pair production at hadron colliders. We examine aspects of signal and background for the SSdB signature at high luminosity LHC (HL-LHC). We evaluate the HL-LHC reach in the SSdB channel for $3000$ $fb^{-1}$. The rather clean production/decay topology admits a wino mass measurement from direct counting rate. The mass measurement may also be verified using distributions in variables such as $m_{T_{2}}$.
