Cover Story: Rather general arguments favor a string landscape selection of soft SUSY breaking terms tilted to large values but tempered by the atomic principle that the derived value of the weak scale in each pocket universe lies not too far from its measured value in our universe. But that leaves (at least) three different paradigms for gaugino masses in natural SUSY models: unified, anomaly mediation and mirage mediation form. Landscape scans for each of these show they populate different, but overlapping, positions in m(ℓℓ) and m(wino) space. The first of these may be directly measurable at high-lumi LHC via the soft opposite-sign dilepton plus jets plus MET signature arising from higgsino pair production, while the second of these could be extracted from direct wino pair production leading to same-sign diboson production.
