EVIDENCE FOR PION-PION INTERACTIONS FROM S-WAVE PION-NUCLEON SCATTERING
Abstract
By fitting the s-wave partial amplitudes for N scattering, in an unphysical region, we have greatly extended the energy range over which we can examine the contribution from the process + N + N. Our method shows up contributions from this process in states of isotopic spin T = 0 and T = 1. We can estimate the energies t1/2 for which this process is important. The form of these contributions is just what would be expected from considerations of angular momenta. Estimates of the amplitudes for + N + N are deduced. The T = 0 amplitude is large, but in the T = 1 case the amplitude is much smaller than the values which were predicted from the nucleon isovector form factors. (Author)
