R{sub b} in supergravity grand unification with nonuniversal soft supersymmetry breaking
- Department of Physics, Northeastern University, Boston, Massachusetts 02115 (United States)
An analysis of supersymmetric contributions to R{sub b} in supergravity grand unification with nonuniversal boundary conditions on soft supersymmetry breaking in the scalar sector is given. Effects on R{sub b} of Planck scale corrections on gaugino masses are also analyzed. It is found that there exist regions of the parameter space where positive corrections to R{sub b} of size {approximately}1{sigma} can be gotten. The region of the parameter space where enhancement of R{sub b} occurs is identified. Predictions of sparticle masses for the maximal R{sub b} case are given. The analysis has implications for the discovery of supersymmetric particles at colliders. {copyright} {ital 1997} {ital The American Physical Society}
