Effects of largeCP-violating soft phases on supersymmetric electroweak baryogenesis

We reexamine the results of recent electroweak baryogenesis calculations and include all allowed large $\mathrm{CP}$-violating supersymmetric phases. If the phases are large, the resulting baryon asymmetry can be considerably larger than the observed value $n_B/s\sim 4\times {10}^{-11}.$ Much of the asymmetry must therefore be washed out, and we argue that the upper bound on the light Higgs boson mass is larger than the value reported in previous work.
