Recoil corrections to pion-nucleon interactions in the CBM
Abstract
Pion-nucleon elastic scattering is considered within the cloudy bag model (CBM) with recoil corrections included. The consideration of recoil corrections is shown to reduce to the renormalization of the πNN-vertex constant whose value is in a better agreement with experiment than that in the static approximation. The contribution of the recoil corrections to scattering lengths in the J = 1/2 channel is found to be about 30%, and in the J = 3/2 channel it is insignificant.
