Search for a light Higgs resonance in radiative decays of theϒ(1S)with a charm tag
A search is presented for the decay Υ(1S)→γA0, A0→c¯c, where A0 is a candidate for the CP-odd Higgs boson of the next-to-minimal supersymmetric standard model. The search is based on data collected with the BABAR detector at the Υ(2S) resonance. A sample of Υ(1S) mesons is selected via the decay …
