Nature of physical problem:
The masses of the neutral CP-even Higgs bosons in the MSSM can be calculated in terms of the other model parameters. Large corrections to the masses at the one-loop level require a two-loop calculation.

Method of solution
A Feynman-diagrammatic calculation has been performed at the two-loop level in O(alphaalphas). The resulting formula has been converted into a Fortran 77 code. This result has been combined with the existing Fortran code for the complete diagrammatic one-loop calculation, additional corrections beyond O(alphaalphas) have also been included.

Restrictions on the complexity of the program
No complex parameters are allowed.

Typical running time
0.5 seconds.
