Abstract.

An Aoki–Denner form of the renormalization scheme is suggested for the physical amplitudes in the minimal supersymmetric standard model. With the more explicit wave-function renormalization, the scheme is parameterized by the mass of the physical pseudoscalar (\(M_A\)) and the mass of heavy CP-even neutral Higgs (\(M_H\)) instead of the conventional \(M_A\), \(\tan\beta\) as input. The counterterm of \(\tan\beta\) is defined on mass shell perturbatively just within the Higgs sector. The renormalization of gauge-scalar mixings are fixed by proper Ward–Takahashi identities. The effect of the reparameterization is also probed to the radiative correction of the mass of the lightest Higgs.
