The $A_{1}$ meson produced at 63 and 94 GeV/c in the reaction $\pi^{-} p\to\pi^{-}\pi^{-}\pi^{+}p$
The results are presented of partial wave analyses of almost 600000 events from the reaction pi /sup -/p to pi /sup -/ pi /sup -/ pi /sup +/p at 63 and 94 GeV/c and with a higher momentum transfer trigger. The shape of the 1/sup +/S ( rho pi ) mass spectrum changes substantially as a function of t,...
