How to generate four-fermion phase space. (English) Zbl 1050.81505
Summary: We present a scheme for integrating the matrix element of an arbitrary \(e^+e^-\to f _1f_2\bar f_3\bar f_4\) process over the complete four-fermion phase space, or its any part, by means of the Monte Carlo technique. The presented algorithm has been successfully implemented in the KORALW Monte Carlo code. The description is also aimed to be helpful for a reader of non-mathematical background, interested in the basic concepts of multichannel Monte Carlo algorithms.
