Abstract:
The Monte Carlo program KoralW version 1.42 is presented. It generates all four-fermion final states with multibranch dedicated Monte Carlo pre-samplers 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.- electron positron: annihilation
- fermion: multiple production
- final state: (4fermion)
- photon: multiple production
- bremsstrahlung
- leading logarithm approximation
- W: pair production
- W: decay
- boson: statistics
- quantum electrodynamics
