Observation of narrow (3$\pi$)$\pm$ peaks in the $\delta$ and A$\_{1}$ regions in $\overline{p}p$ annihilations at 5.7 GeV/c

In the pi /sup +/ pi /sup -/ pi /sup +or-/ systems of the reactions pp to KKm pi (m=4,5) two narrow peaks are observed at the positions of the delta and A/sub 1/ mesons. The measured masses and widths are: M= (956+or-7)MeV, Gamma =(46+or-22)MeV for the delta and M=(1076+or-5)Me V, Gamma =(36/sup +20...
