Forward pion-nucleon charge exchange reaction and Regge constraints
pion-nucleon interaction Regge model
2009/11/24
We present our recent study of pion-nucleon charge exchange amplitudes above 2 GeV. We analyze the forward pion-nucleon charge exchange reaction data in a Regge model and compare the resulting amplitu...
Phase-Shift Definition for Pion-Nucleon Scattering from Chiral Perturbation Theory
Phase-Shift Definition Pion-Nucleon Chiral Perturbation Theory
2010/10/19
Chiral Perturbation Theory is considered as a very precise method when applied to pion-nucleon scattering near threshold and in the unphysical region since in these cases the pion momenta are small. I...
