Neutralino dark matter scattering and B s → μ + μ − in SUSY models
Abstract
It is pointed out that there is a strong correlation between the neutralino dark matter scattering cross section

and the branching ratio for

within minimal supergravity (mSUGRA) and its extensions. This correlation arises mainly from
tanβ
and heavy neutral Higgs mass dependence, and shows a nice interplay between vastly different two observables within supersymmetric models. Current upper limit on
