Probing the scalar-pseudoscalar mixing in the 125 GeV Higgs particle with current data. Physical Review D . 2012; 1 (86).1550-7998http://hdl.handle.net/10400.21/1907LHC 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 CP violation and soft Z(2) violation. Including all Higgs production mechanisms, we determine the current constraints obtained by comparing h -> yy with h -> VV*, and comment on the information which can be gained by measurements of h -> b (b) over bar. We find bounds vertical bar s(2)vertical bar less than or similar to 0.83 at one sigma, where vertical bar s(2)vertical bar = 0 (vertical bar s(2)vertical bar = 1) corresponds to a pure scalar (pure pseudoscalar) state.engElectroweak Symmetry-BreakingStandard ModelCP ViolationRoots-S=7 TevLHCBosonAnatomyjournal article
