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 a set of  selected processes: 

and complete electroweak


process. 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 or  HERWIG  Monte Carlo event generator. Interfaces to both of these generators are provided in the distribution version. The matrix element codes have been derived with the help of the MADGRAPH package.The phase-space generation is based on the multi-channel self-optimising approach as proposed in NEXTCALIBUR event generator. Eventually, additional smoothing of the phase space was obtained by using a modified  ac-VEGAS routine in order to improve the generation efficiency.
