Chiral effective field theory of ∆(1232) and Compton scattering
Chiral perturbation theory (χPT) is limited to a low-energy domain p ≪ Λ, where p is the momentum of the particles and Λ stands for all the heavy scales such as the masses of the “integrated out” degrees of freedom. In a theory without explicit ∆(1232) fields the limit is set by the excitation energy of the ∆-resonance: ∆ ≡ M∆ −MN ≈ 293 MeV. This limit is clearly seen in Compton scattering off ...
متن کاملThree- and four-nucleon systems from chiral effective field theory.
Recently developed chiral nucleon-nucleon (NN) forces at next-to-leading order (NLO), that describe NN phase shifts up to about 100 MeV fairly well, have been applied to 3N and 4N systems. Faddeev-Yakubovsky equations have been solved rigorously. The resulting 3N and 4N binding energies are in the same range as found using standard NN potentials. In addition, low-energy 3N scattering observable...
متن کاملFew–Nucleon Forces and Systems in Chiral Effective Field Theory
We outline the structure of the nuclear force in the framework of chiral effective field theory of QCD and review recent applications to processes involving few nucleons.
متن کاملCharge–dependent nucleon–nucleon potential from chiral effective field theory
We discuss charge symmetry and charge independence breaking in a chiral effective field theory approach for few–nucleon systems based on a modified Weinberg power counting. We construct a two–nucleon potential with bound and scattering states generated by means of a properly regularized Lippmann–Schwinger equation. We systematically introduce strong isospin–violating and electromagnetic operato...
متن کاملThree–Nucleon Forces from Chiral Effective Field Theory
We perform the first complete analysis of nd scattering at next–to–next–to–leading order in chiral effective field theory including the corresponding three–nucleon force and extending our previous work, where only the two–nucleon interaction has been taken into account. The three–nucleon force appears first at this order in the chiral expansion and depends on two unknown parameters. These two p...
