New applications of CARLOMAT

Abstract: Modifications of CARLOMAT, a program for automatic computation of the lowest order cross sections of multiparticle reactions, that include an abridgement of the phase space integration routine, an interface to parton density functions, improvement of the color matrix computation, supplementation of the Cabibbo-Kobayashi-Maskawa mixing in the quark sector, implementation of effective models such as scalar electrodynamics, the $Wtb$ interaction with operators of dimension up to 5 and a general top--Higgs coupling, are discussed. The modifications, together with recent developments concerning mainly description of the $e^+e^-$ annihilation into hadrons at low energies, broaden the spectrum of possible applications of the program.
