A Monte Carlo event generator is implemented for a two-Higgs-doublet model with maximal CP symmetry, the MCPM. The model contains five physical Higgs bosons; the rho', behaving similarly to the standard-model Higgs boson, two extra neutral bosons h' and h '', and a charged pair H-+/-. The special feature of the MCPM is that, concerning the Yukawa couplings, the bosons h', h '' and H-+/- couple directly only to the second-generation fermions but with strengths given by the third-generation-fermion masses. Our event generator allows the simulation of the Drell-Yan-type production processes of h', h '' and H-+/- in proton-proton collisions at LHC energies. Also the subsequent leptonic decays of these bosons into the mu(+)mu(-), mu(+)nu(mu) and mu(-)(nu) over bar (mu) channels are studied as well as the dominant background processes. We estimate the integrated luminosities needed in pp collisions at center-of-mass energies of 8 and 14 TeV for significant observations of the Higgs bosons h', h '' and H-+/- in these muonic channels.
