The decay b --> s$\gamma$ in SUSY extensions of the standard model / Nath, Pran (CERN) ; Arnowitt, Richard L. (Texas A-M)
A brief review is given of the decay b-s+gamma in SUSY extensions of the Standard Model.It is found that the recent CLEO results put strong constraints on the parameter space of the minimal N=1 Supergravity unified theory.Dark matter analyses are also strongly constrained for mu>0..

b --> s$\gamma$ decay in supergravity grand unification and dark matter / Nath, Pran ; Arnowitt, Richard Lewis
An analysis of the b \rightarrow s\gamma is given in supergravity grand unification using the framework of the radiative breaking of the electro-weak symmetry under three separate sets of constraints:1) neutralino relic density does not overclose the universe,2)p-stability constraint, and 3) the combined constraints of p-stability and COBE data .For case 1 it is found that the CLEO II data on the branching ratio already imposes very strong further constraints on dark matter analyses. For case2 the branching ratio is found to lie in the range (1.5-6.3)x10^{-4} and thus the data does not at present significantly limit the analyses with p-stability constraint. [...]

Event rates in dark matter detectors for neutralinos including constraints from the b --> s$\gamma$ decay / Nath, Pran (CERN) ; Arnowitt, Richard L. (Texas A-M)
Event rates for dark matter detectors in neutralino--nucleus scattering are studied for supergravity unified models, including the constraint arising from the $b\rightarrow s\gamma$ experiment. The recent experimental measurement of this decay by the CLEO Collaboration leads to strong constraints on the SUSY particle spectrum,and also significantly affects the event rates in dark matter detectors.

Constraints on the minimal supergravity model from the $b \to s\gamma$ decay / Wu, Ji-zhi (Texas A-M) ; Arnowitt, Richard L. (Texas A-M) ; Nath, Pran (CERN ; Northeastern U.)
The constraints on the minimal supergravity model from the b->s+\gamma decay are studied. A large domain in the parameter space for the model satisfies the CLEO bound, BR(b->s+\gamma)<5.4X10~{-4}. [...]
