چکیده
The Jülich-Bonn group aims at an extensive study of the baryonbaryon ( BB ) interaction involving strange baryons (Λ, Σ, Ξ) within SU(3) chiral effective field theory. An overview achievements and new developments over past few years is provided. topics covered are: 1) Derivation leading charge-symmetry breaking (CSB) for Λ N system its application in a CSB effects A =4 Λ-hypernuclei. 2) Updated results Ξ NLO predictions − p correlation functions. 3) Extension -Σ to next-to-next-to-leading order.

Hyperon-nucleon interaction in chiral effective field theory
Chiral effective field theory (EFT) as proposed in the pioneering works of Weinberg [1] is a powerful tool for the derivation of baryonic forces. In this scheme there is an underlying power counting which allows to improve calculations systematically by going to higher orders in a perturbative expansion. In addition, it is possible to derive twoand corresponding three-body forces as well as ext...
متن کاملHyperon-nucleon interactions – a chiral effective field theory approach
We construct the leading order hyperon-nucleon potential in chiral effective field theory. We show that a good description of the available data is possible and discuss briefly further improvements of this scheme.
متن کاملHyperon-nucleon interactions in effective field theory
Abstract. We have constructed the leading order hyperon-nucleon potential in a chiral Effective Field Theory approach. The chiral potential consists of one-pseudoscalar-meson exchanges and non-derivative four-baryon contact terms. The hyperon-nucleon interactions are derived using SU(3) symmetry, the nucleon-nucleon interaction is not considered explicitly since it can not be described well wit...
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 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...
