Motivation The BMSSM Dark Matter Direct Detection Indirect Detection Summary

Correlated stop-slepton masses: mSUGRA-like

The mSUGRA model is specified by 5 parameters: tan β: ratio of the Higgs vevs m1/2: common mass for the gauginos (bino, wino and gluino) m0: universal scalar mass (sfermions and Higgs bosons) A0: universal trilinear coupling sign µ: sign of the µ parameter In mSUGRA scenarios usually the lightest neutralino is the LSP Because of the LEP constraint over the Higgs mass, the bulk region (i.e. low m0 and low m1/2) is ruled out.
