Abstract:

A possible explanation of the anomaly found in meson production in proton-deuteron collisions is that put forward by Tubis and Uretsky Phys. Rev. Letters. 5513, 1960. They suggest that if a final state P wave pion-pion interaction, described in the scattering length approximation, is added to the statistical model of Abashian et al. Ibid., 5258, 1960, a P wave scattering length of magnitude 2.5 pion Compton wavelengths explains the anomaly. Evidence is given that does not agree with such a large value for this scattering length. This evidence comes from equations relating the three scattering lengths as derived from crossing symmetry, and from the experimental evidence on the asymmetry of the pion momentum spectrum in tau decay.
