Abstract The version 1.51 of the Monte Carlo (MC) program KoralW for all e^+ e^-→ f_1 f̄_2 f_3 f̄_4processes is presented. The most important change from the previous version 1.42 is the facility for writing MC events on the mass storage device and reprocessing them later on. In the reprocessing parameters of the Standard Model may be modified in order to fit them to experimental data. Another important new feature is the possibility of including complete O(α) corrections to double-resonant W-pair... Title of program: KoralW, version 1.51 Catalogue Id: ADCT_v3_0 [ADOZ] Nature of problem The precise study of W-pair production and decay at LEP2 requires both non-double-resonant and O(alpha) corrections. So far each of these corrections is available as a separate Monte Carlo program and there is no Monte Carlo that could simulate in a complete way both effects at the same time. Such a MC event generator would be of importance, for example, for apparatus simulations or Monte Carlo based fits. The previous version of KoralW [1] included all non-double-resonant corrections to all dou ...
