Search for di muon decays of a light scalar higgs boson in radiative y 1s decays

Abstract

We search for di muon decays of a low mass Higgs boson A0 in the fully reconstructed decay chain of D 2S 3S D D DDD 1S D 1S D DA0 A0 D D DD The A0 is predicted by several extensions of the Standard Model SM including the Next to Minimal Supersymmetric Standard Model NMSSM NMSSM introduces a CP odd light Higgs boson whose mass could be less than 10 GeV c2 The data samples used in this analysis contain 92 8 D 106 D 2S and 116 8 D 106 D 3S events collected by the BABAR detect
