Search for a Light Higgs Boson in Radiative $\Upsilon$ Decays

We have collected $\sim 30~\mathrm{fb}^{-1}$ of data with the {\it B{\footnotesize A}B{\footnotesize AR}} detector at the PEP- II asymmetric $e^+e^-$ collider operating at a center-of-mass energy of 10.355 GeV. This data sample contains approximately 122 million $\Upsilon(3S)$ candidates. We will present a search for light Higgs in the decays $\Upsilon(3S)\to\gamma A^0 $. We will present the techniques and methods, as well as the results and conclusions from this search.
