Predictions for LHC physics are given for a two-Higgs-doublet model havingfour generalized CP symmetries. In this maximally-CP-symmetric model (MCPM) thefirst fermion family is, at tree level, uncoupled to the Higgs fields and thusmassless. The second and third fermion families have a very symmetric couplingto the Higgs fields. But through the electroweak symmetry breaking a large masshierarchy is generated between these fermion families. Thus, the fermion massspectrum of the model presents a rough approximation to what is observed inNature. In the MCPM the couplings of the Higgs bosons to the fermions arecompletely fixed. This allows us to present clear predictions for theproduction at the LHC and for the decays of the physical Higgs bosons. Assalient feature we find rather large cross sections for Higgs-boson productionvia Drell-Yan type processes. In this paper we present a short outline of themodel and extend a former study by the predictions at LHC for a center-of-massenergy of 7 TeV.
