Theory of the Pion-Nucleus Optical Potential with Crossing
Journal Article
·
· Physical Review Letters
A theory of the pi -nucleus optical potential is developed from the exact propagator of a pion in the presence of a nucleus. The crossed pi - nucleus diagrams, absent in previous work, are shown to have significant effect on the cross sections and the elastic-scattering wave functions of low-energy pions.
