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 کاملEffective chiral theory of nucleon-nucleon scattering
We present a new chiral expansion scheme for the nucleon-nucleon scattering amplitude which preserves unitarity exactly. Our effective field theory builds on the power counting rules for 2-nucleon reducible diagrams proposed in [1]. We evaluate the leading order terms of the isospin one scattering amplitude and elaborate in detail on the S0 phase shift. Our chiral description of the S0phase shi...
متن کاملChiral Symmetry and Three-Nucleon Forces
After a brief review of the role three-nucleon forces play in the few-nucleon systems, the chiral-perturbation-theory approach to these forces is discussed. Construction of the (nominal) leadingand subleading-order Born terms and pion-rescattering graphs contributing to two-pion-exchange three-nucleon forces is reviewed, and comparisons are made of the types of such forces that are used today. ...
متن کاملChiral Symmetry and the Nucleon-Nucleon Interaction
The main progress in the eld of nucleon-nucleon (NN) potentials, which we have seen in recent years, is the construction of some very quantitative (high-quality/high-precision) NN potentials. These potentials will serve as excellent input for microscopic nuclear structure calculations and will allow for a systematic investigation of o -shell effects. After this enormous quantitative work, it is...
