Migdal's short range correlations in a covariant model
M. F. M. Lutz
Abstract
We construct a covariant model for short range correlations of a pion emerged in nuclear matter. Once the delta-hole contribution is considered an additional and so far neglected channel opens that leads to significant modifications in the vicinity of the kinematical region defined by ω | q |. We speculate that this novel effect should be important for the quantitative interpretation of charge exchange reactions like C(He,t).
