      SUBROUTINE SSHIBF
C-----------------------------------------------------------------------
C
C     This subroutine calculates the decay widths for decays of the 
C     Higgs scalars present in the minimal SUSY model.
C
C     NOTE: Decays into sfermions are not yet incorporated.
C
C     Standard model parameters are hard wired in  SSMSSM. To get
C     the 1987-8 values corresponding to the Gunion et al. papers
C     (Intl. J. Mod. Phys. 2(4):1035; Nucl. Phys. B307:445) you must
C     change
C          ALFA3 = 0.12  --> 0.136
C          AMW   = 80.0  --> 81.3
C          AMZ   = 91.17 --> 92.7
C
C     2/9/91:
C     I've modified the program slightly.  The ALPHA3 = 0.12 value
C     above is the recent empirical value from LEP. Using the equation
C     from page 220 in Barger and Phillips yields ALPHA3 = 0.136.
C
C     10/1/92:
C     Now includes vertex corrections for triple Higgs couplings.
C     (See Kunszt and Zwirner, CERN-TH.6150/91 for all but HH-HC-HC
C     correction which is in our Higgs --> SUSY paper: Baer et al. 
C     FSU-HEP-920630 or UH-511-749-92)
