Production of $3\pi^{0}$ and $\eta2\pi^{0}$ from $\pi^{-}p$ collision in GAMS experiment

The data on the pi- p --> M0 n, with M0 = pi0 pi0 pi0 or pi0 pi0 eta obtained in the GAMS experiment may be useful to study the sigma(400--700) and a_1^chi (1000), which can be taken as chiral partners of pi and rho, respectively. A preliminary analysis for 3pi0 invariant mass spectra gives a sup...
