INTERPRETATION OF THE BERKELEY ANOMALY IN HIGH-ENERGY p-d COLLISIONS
Journal Article

· Phys. Rev. Letters
An explanation of the peak in the momentum spectrum of the final nucleus (He/sup 3/ or T) observed in Berkeley experiments on double-pion production in p- d collisions at a momentum corresponding to a total energy of approximately 310 Mev of the two pions is offered in which the statistical method is generalized to allow for p-wave scattering between the finalstate pions. The scattering length is chosen to give a production cross section maximum at about 300-Mev two-pion energy and found to be approximately 2.5 pion Compton wavelengths. It is concluded that it is not necessary to postulate a resonance to explain the Berkeley bumps. The possibility of a two-meson bound state is discussed. (D.L.C.)
