Analytical expressions for radiatively corrected Higgs masses and couplings in the MSSM

We propose, for the computation of the Higgs mass spectrum and couplings, a renormalization-group improved leading-log approximation, where the renormalization scale is fixed to the top-quark pole mass. For the case mA ∼ MSUSY, our leading-log approximation differs by less than 2 GeV from previous results on the Higgs mass computed using a nearly scale independent renormalization-group improved effective potential up to nextto-leading order. Moreover, for the general case mA < MSUSY, we provide analytical formulae (including two-loop leading-log corrections) for all the masses and couplings in the Higgs sector. For MSUSY < 1.5 TeV and arbi
