In this work, the B-> / X_dell ell decays are examined in the context of a
CP softly broken two Higgs doublet model. The differential
branching ratio, forward-backward asymmetry, CP-violating
asymmetry, CP-violating asymmetry in the forward-backward
asymmetry and polarization asymmetries of the final lepton in this
decay are studied. The dependencies of these physical parameters
on the model parameters are analyzed by paying a special attention
to the effects of neutral Higgs boson (NHB) exchanges and possible
CP violating effects. It has been found that NHB effects are
quite significant for the tau mode and the above-mentioned
observables seems to be promising as a testing ground for new
physics beyond the SM, especially for the existence of the
CP-violating phase in the theory.
