Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Shao-Fei Chen, Bo-Chao Liu, , | Summary: In this work, we study the spin density matrix element $rho_{00}$ of the $phi$ in the decay $J/psi rightarrow eta pi phi$. In previous studies, a band around 1.4 GeV on the $pi^0phi$ distribution in Dalitz plot was […]
