Abstract

We study the potential of radiative decays of the ϒ_1S and of the ϕ mesons to search for a light pseudoscalar Higgs boson, proposed as a possible interpretation of Σ⁺→pμ⁺μ^- events observed by the HyperCP collaboration at Fermilab. We conclude that the detection of this signal should certainly be possible with the current CLEO ϒ_1S data, and is within the reach of KLOE in at least part of the range of couplings suggested by the HyperCP findings.
