Calculate the energy and momentum of the pions in the ∆++ centre-of-mass frame. We need the masses of the particles, from the particle properties sheet: m π = 139.6 MeV/c2, m p = 938.3 MeV/c2 … WebbWe revisit the D D * interactions in chiral effective field theory up to the third order for the first time. We deal with the pion-exchanged interactions via local momentum-space regularization, in which we focus on their long-range behaviors through demanding their contributions vanish at the origin in the coordinate space.

The model we have developed may be considered as a first step in developing a pion-nucleus optical potential that treats the nucleons like Dirac particles. It will also have application in processes like free pion photo-production. Webb2718 Page 4 of 9 Eur. Phys. J.
