Abstract
We search for a low-mass scalar -odd Higgs boson, , produced in the radiative decay of the upsilon resonance and decaying into a pair: . The production of mesons is tagged by transitions, using a sample of mesons collected by the BABAR detector. We find no evidence for a Higgs boson in the mass range , and combine these results with our previous search for the tau decays of the light Higgs in radiative decays, setting limits on the coupling of to the quarks in the range 0.09–1.9. Our measurements improve the constraints on the parameters of the next-to-minimal-supersymmetric Standard Model and similar theories with low-mass scalar degrees of freedom.
