Description:

• The programs in the library calculate differential and total cross sections for the neutral MSSM Higgs boson productions:

  e⁺e^- -> Z^*h(H)-> ffh(H)
  e⁺e^- -> Zh(H)
  e⁺e^- -> Ah(H)

• Programs calculate also decays widths and decays branching ratios of h, H and A into all allowed 2-body final states.

Programs include all 1-loop contributions to the masses and cross sections and some leading (reducible) higher order terms.

The program consists of the following packages:

• 2- and 3-point Green function calculation, physical Higgs boson masses, formulas for cross sections excluding box contributions: mssm.tar.gz (P.H. Chankowski, S. Pokorski, J. Rosiek).

• Box contributions calculation: box.tar.gz (V. Driesen, W. Hollik).

• The library ffv1_9.tar.gz (G.J. van Oldenborgh, for e-mail and address see the README file in ffv1_9.tar.gz). This library contains procedures for the calculations of the standard loop integrals.

Description of use of this library and examples can be found in the following files:

• README. Short explanation how to compile libraries and example program.

• example.f. Program containing examples of use of all basic procedures of the library. Understanding of this program should be sufficient for effective use of the whole library, the rest of it can be treated as a black box unless the user wants to modify himself some details of calculations.

• example.dat. Standard output produced by example.f, can be used for cross-checking of compability and relative accuracy of various compilers.
