Branching fraction measurements of \chi_{c0} and \chi_{c2} to \pi^0\pi^0 and \eta\eta
Branching fraction \chi_{c2} \eta\eta
2010/1/29
Using a sample of 1.06 \times 10^8 \psi^{\prime} decays collected by the BESIII detector, \chi_{c0} and \chi_{c2} decays into \pi^0\pi^0 and \eta\eta are studied. The branching fraction results are Br...
