KORALW Monte Carlo event generator for $e^+e^- \rightarrow$ 4-fermions.

Source codes:

• KORALW Version 1.42.3
  with all 4-fermion matrix elements (generated by GRACE v 2.0) and sophisticated phase-space presamplers accounting for different kinematical singularities in all 4-fermion processes. All 4-fermion final states can be generated in the same run. To down load it click here koralw-1.42.3-export.tar.gz; 3.35MB. Note: This version needs about 50Mb of disk space to compile succesfully.
