Abstract
Version 2 of 'carlomat', a program for automatic computation of the lowest order cross sections of multiparticle reactions, is described. The substantial modifications with respect to version 1 of the program include: generation of a single phase space parametrization for the Feynman diagrams of the same topology, an interface to parton density functions, improvement of the color matrix computation, the Cabibbo-Kobayashi-Maskawa mixing in the quark sector, the effective models including scalar electrodynamics, the Wtb interaction with operators of dimension up to 5 and a general top-higgs coupling. Moreover, some minor modifications have been made and several bugs in the program have been corrected.
