Study of Scalar Mesons at BES-II

Abstract

Recent results from BES-II experiment on hadron spectroscopy using $\jpsi$ and ${\psi }^{\prime }$ data samples collected in $e^{+}{e}^{-}$ annihilation are presented, including study of the scalar particles in $\jpsi$ radiative and hadronic decays, the observation of X(1810) in $J/\psi \to \gamma \varphi \omega$, as well as pair productions of scalars in ${\chi }_{c0}$ hadronic decays.
