Nuclear transparencies from photoinduced pion production

Abstract

We present a relativistic and cross-section factorized framework for computing nuclear transparencies extracted from A(γ,πN) reactions at intermediate energies. The proposed quantummechanical model adopts a relativistic extension to the multiple-scattering Glauber approximation to account for the final state interactions of the ejected nucleon and pion. The theoretical predictions are compared against the experimental ^4He(γ,p π^-) data from Jefferson Lab. For those data, our results show no conclusive evidence for the onset of mechanisms related to color transparency.
