Low mass New Physics search for a CP-odd Higgs boson $A^0$ deacying to $s\bar{s}$ or gluon gluon at BaBar

Abstract

We report on the search for the decay ${\rm Y}(1S)\to \gamma A^0$, $A^0\to gg$ or $s\bar{s}$, where $A^0$ is the pseudoscalar light Higgs boson predicted by the next-to-minimal supersymmetric standard model. A sample of $\sim 18\times 10^6$ ${\rm Y}(1S)$ resonances, produced in the BaBar experiment via $e^{+}{e}^{-}\to {\rm Y}(2S)\to {\pi }^{+}{\pi }^{-}{\rm Y}(1S)$, is used for this search. No significant signal has been found, and upper limits at the $90\%$ of confidence level are set on the product branching fraction of the process.
