摘要：
Supersymmetric models with an additional singlet field offer the Higgs boson the possibility to decay to two pseudoscalars, a. If the mass of these pseudoscalars is above the b (b) over bar threshold, a -> b (b) over bar is generically the dominant decay mode. The decay h -> aa -> b (b) over barb (b) over bar may be seen above backgrounds at the Tevatron if the Higgs production cross section is enhanced relative to that of the standard model.
