The reaction pi N -> pi pi N in chiral effective field theory with explicit Delta(1232) degrees of freedom
arXiv:1403.2510 · doi:10.1103/PhysRevC.89.065211
Abstract
The reaction pi N -> pi pi N is studied at tree level up to next-to-leading order in the framework of manifestly covariant baryon chiral perturbation theory with explicit Delta(1232) degrees of freedom. Using total cross section data to determine the relevant low-energy constants, predictions are made for various differential as well as total cross sections at higher energies. A detailed comparison of results based on the heavy-baryon and relativistic formulations of chiral perturbation theory with and without explicit Delta degrees of freedom is given.
