摘要：
We reexamine the one-loop corrections to the mass of the pseudo-scaler Higgs boson, using the effective potential. In the absence of the chargino and neutralino contributions its mass exhibits a large scale dependence in the large M-1/2 regime, especially for values of tan beta > 20. Thus, although of electroweak origin, the heaviness of the M-1/2, in conjunction with the largeness of tan beta, makes these corrections very important for establishing a scale independent result and an unambiguous determination of the pseudo-scalar mass in this region of the parameter space.
