GAUGE UNIFICATION AND DYNAMICAL SUPERSYMMETRY BREAKING - ART. NO. 075007

Under the assumption that all the gauge groups in supersymmetric theor ies unify at the fundamental scale, the numbers and the mass scales of messenger quarks and leptons, as well as the beta-function coefficien t of the sector for dynamical supersymmetry breaking, are constrained depending on various gauge mediation mechanisms. For this, we use one- loop renormalization group equations and draw constraints on the scale s in each gauge mediation model. [S0556-2821(98)00719-X].
