Pion production in nucleon-nucleon collisions in chiral effective field theory with Delta(1232)-degrees of freedom

A. A. Filin, V. Baru, E. Epelbaum +3

A calculation of the pion-production operator up to next-to-next-to-leading order for s-wave pions is performed within chiral effective field theory. In the previous study [Phys. R…
