Charge–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...
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 کاملChiral kinetic theory.
We derive the nonequilibrium kinetic equation describing the motion of chiral massless particles in the regime where it can be considered classically. We show that the Berry monopole which appears at the origin of the momentum space due to level crossing is responsible for the chiral magnetic and vortical effects.
متن کاملScattering From Effective Field Theory
We examine the role of the ∆∆ intermediate state in NN scattering in the S0 channel. The computation is performed at lowest order in an effective field theory involving local four-fermion operators and one pion exchange using dimensional regularization with MS. As first discussed by Weinberg, in the theory with only nucleons the large scattering length in this channel requires a small scale for...
