Request Description and Potential
Reason for request:
Natural supersymmetry, which cancels the largest divergences in the Higgs mass in the Standard Model, favors spectra with light scalar top quarks. In particular, the left-handed scalar top is associated with the left-handed scalar bottom quark, which should also be light. Spectra with a decay chain sbottom -> stop + W followed by stop -> top + neutralino or gravitino can give rise to same-sign leptons. Thus, it would be worthwhile to reanalyze the same-sign lepton searches to understand how they can constrain natural supersymmetry. (See also request 1203.0025.)
