Neutralino dark matter in minimal supergravity: Direct detection versus collider searches
- Department of Physics, Florida State University, Tallahassee, Florida 32306 (United States)
We calculate expected event rates for direct detection of relic neutralinos as a function of parameter space of the minimal supergravity model. Numerical results are presented for the specific case of a {sup 73}Ge detector. We find significant detection rates (R{gt}0.01events/kg/day) in regions of parameter space most favored by constraints from B{r_arrow}X{sub s}{gamma} and the cosmological relic density of neutralinos. The detection rates are especially large in regions of large tan{beta}, where many conventional signals for supersymmetry at collider experiments are difficult to detect. If the parameter tan{beta} is large, then there is a significant probability that the first direct evidence for supersymmetry could come from direct detection experiments, rather than from collider searches for sparticles. {copyright} {ital 1997} {ital The American Physical Society}
