Search for Hadronic Decays of a Light Higgs Boson in the Radiative Decay Υ → γA0

Creators

Description

The authors search for hadronic decays of a light Higgs boson (A0) produced in radiative decays of an Υ(2S) or Υ(3S) meson, Υ → γA0. The data have been recorded by the BABAR experiment at the Υ(3S) and Υ(2S) center of mass energies, and include (121.3 ± 1.2) x 106 Υ(3S) and (98.3 ± 0.9) x 106 Υ(2S) mesons. No significant signal is observed. We set 90% confidence level upper limits on the product branching fractions β(Υ(nS) → γA0) · β(A0 → hadrons) (n = 2 or 3) that range from 1 x 10-6 for an A0 mass of 0.3 GeV/c2 to 8 x 10-5 at 7 GeV/c2.
