Query: Partial Wave Analysis of $J/\psi\to\gamma(\pi^+\pi^-\pi^+\pi^-)$   BES data on $J/\psi \to \gamma (\pi^{+} \pi^{-} \pi^{+} \pi^{-})$ 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 $\sigma\sigma$, while $2^{++}$
resonances in the high mass region decay mainly to $f_2(1270)\sigma$ and
$\sigma\sigma$; $2^{++}$ resonances from the low mass region decay dominantly
to $\rho\rho$.
