Programming language used: Fortran
Computer:
Sigma station (Alpha) .
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.
