Abstract
LHC has found hints for a Higgs particle of 125 GeV. We investigate the possibility that such a particle is a mixture of scalar and pseudoscalar states. For definiteness, we concentrate on a two-Higgs doublet model with explicit violation and soft violation. Including all Higgs production mechanisms, we determine the current constraints obtained by comparing with , and comment on the information which can be gained by measurements of . We find bounds at one sigma, where () corresponds to a pure scalar (pure pseudoscalar) state.
