Understanding the Optical Potential in HBT Interferometry
arXiv:0809.0520 · doi:10.1103/PhysRevC.78.054905
Abstract
The validity of using a pion optical potential to incorporate the effects of final state interactions on HBT interferometry is investigated. We find that if the optical potential is real, the standard formalism is modified as previously described in the literature. However, if the optical potential is complex, a new term involving pion emission from eliminated states must be included. The size of such effects in previous work by Cramer and Miller is assessed.
