Description
We search for a CP-odd light Higgs among 102 M $\Upsilon(1S)$ events recorded with
the Belle detector at KEKB. Our signal mode is
$\Upsilon(1S)\to\gamma A_0;A_0\to \tau^+\tau^-$, where the $\tau$ is
detected via its leptonic decay modes. We determine the upper limits
on the production rates for a CP-odd light Higgs with a mass between
the $\tau^+\tau^-$ threshold and 9.4 GeV/$c^2$.
This result puts stringent constraints on theoretical models of low
mass NMSSM Higgs bosons.
