Abstract

The AcerMC Monte Carlo Event Generator is dedicated for the generation of Standard Model background processes at pp LHC collisions. The program itself provides a library of the massive matrix elements and phase space modules for generation of selected processes. The hard process event, generated with one of these modules, can be completed by the initial and final state radiation, hadronisation and decays, simulated with either PYTHIA, ARIADNE or HERWIG Monte Carlo event generator and (optionally) with TAUOLA and PHOTOS. Interfaces to all these packages are provided in the distribution version. The matrix element code has been derived with the help of the MADGRAPH package. The phase-space generation is based on the multi-channel self-optimising approach using the modified Kajantie-Byckling formalism for phase space construction and further smoothing of the phase space was obtained by using a modified ac-VEGAS algorithm.
