| dc.description | BES data on $J/ψ\to γ(π^{+} π^{-} π^{+} π^{-})$ have been analyzed into partial waves. We fit with resonances having $J^{PC}=2^{++}$ at 1275 MeV, $0^{++}$ at 1500 MeV, $2^{++}$ at 1565 MeV, $0^{++}$ at 1740 MeV, $2^{++}$ at 1940 MeV and $0^{++}$ at 2104 MeV, plus a broad $0^-$ component. The $0^{++}$ resonances decay dominantly to $σσ$, while $2^{++}$ resonances in the high mass region decay mainly to $f_2(1270)σ$ and $σσ$; $2^{++}$ resonances from the low mass region decay dominantly to $ρρ$. | |
