A quantitative analysis of aμ≡1/2(g-2)μ within the framework of supergravity grand unification and radiative breaking of the electroweak symmetry is given. It is found that aμSUSY is dominated by the chiral interference term from the light chargino exchange, and that this term carries a signature which correlates strongly with the sign of μ. Thus as a rule aμSUSY>0 for μ>0 and aμSUSYμtanβ∼1. At the quantitative level it is shown that if the E821 BNL experiment can reach the expected sensitivity of 4×10⁻1⁰ and there is a reduction in the hadronic error by a factor of 4 or more, …

One-loop corrections to the radiative breaking of electroweak symmetry in supergravity unified models are analyzed. It is shown that in a physically interesting domain of parameter space there is a large cancellation among the contributions of the first two generations of squarks and the three generations of sleptons to the vacuum expectation value (VEV) equations. Partial cancellations in other sectors are also found. These cancellations reduce the effect of the one-loop contributions to the VEV equations.
