Dynamical calculation of the decay psi to psi +2 pi
The authors calculate the psi ' to psi +2 pi decay width on the basis of partial wave dispersion relations in the pi pi channel. This is basically a coupled channel problem involving pi pi , DD, etc. intermediate states. The calculation acquires anomalous thresholds due to the fact that the ver...
