摘要：

The Monte Carlo program KoralW version 1.42 is presented, It generates all four-fermion final states with multibranch dedicated Monte Carlo presamplers and complete, massive, Born matrix elements, The presamplers cover the entire phase space. Multiphoton bremsstrahlung is implemented in the ISR approximation within the YFS formulation with the O(alpha(3)) leading-log matrix element. The anomalous WWV couplings are implemented in CC03 approximation. The standard decay libraries (JETSET, PHOTOS, TAUOLA) are interfaced. The semi-analytical CC03-type code KorWan for differential and total cross sections is included. (C) 1999 Elsevier Science B.V. All rights reserved.
