Study of a^0_0(980)-f_0(980) mixing at BESIII

Abstract

In this talk,we present direct measurements of $a_0^0(980)-f_0(980)$ mixing in the processes $J/\psi \to \varphi f_0(980)\to \varphi a_0^0(980)\to \varphi \eta {\pi }^0$ and ${\psi }^{\prime }\to \gamma {\chi }_{c1},{\chi }_{c1}\to {\pi }^0{a}_0^0(980)\to {\pi }^0{f}_0(980)\to {\pi }^0{\pi }^{+}{\pi }^{-}$ with $2.25\times 10^8$ $J/\psi$ data and $1.06\times 10^8$ ${\psi }^{\prime }$ data at BESIII.
