Abstract
The possible existence of a light CP-odd Higgs state in many new-physics models could lead to observable effects in the bottomonium sector. Experimental bounds on radiative decays through such a pseudoscalar state and possible mixings with the states are reviewed. Combining these two effects, we set constraints on the properties of the CP-odd Higgs in the limit of small photon energy of , that is on the pseudoscalar mass-range GeV.
