Two-loop Barr-Zee type contributions to (g-2)μ in the minimal supersymmetric standard model

Description

We consider the contribution of a two-loop Barr-Zee type diagram to (g-2)μ in the effective supersymmetric models. At relatively large tan β, we show that the contribution of light third generation scalar fermions and neutral CP-even Higgs bosons, h0(H0) can easily explain the very recent BNL experimental data. In our analysis (g-2)μ prefers a negative Af and positive μ. It is more sensitive to the chirality flipping h0(H0)f-tildeR*f-tildeL rather than the chirality conserving couplings
