Abstract
The systematic on-shell renormalization programme for the Higgs sector of the minimal supersymmetric standard model, introduced earlier to study the Higgs boson mass spectrum, is completed with the calculation of all the one-loop corrections to the Higgs boson couplings. The cross sections for the Higgs production at LEP are then calculated and compared with the results obtained in the tree approximation for the couplings in the effective potential and renormalization group approaches. Also, the one-loop corrections to the decay width for H 0→Z 0Z 0 (where H 0 is the heavier neutral scalar) are calculated and signatures of the H 0 production at LHC and SSC are briefly discussed.
