We study the potential of radiative decays of the Upsilon(1S) and of the phimesons to search for a light pseudoscalar Higgs boson, proposed as a possibleinterpretation of Sigma+ --> p mu+mu- events observed by the HyperCPcollaboration at Fermilab. We conclude that the detection of this signal shouldcertainly be possible with the current CLEO Upsilon(1S) data, and is within thereach of KLOE in at least part of the range of couplings suggested by theHyperCP findings.
