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 کاملElectromagnetic nucleon-to-delta transition in chiral effective-field theory.
We perform a relativistic chiral effective-field theory calculation of pion electroproduction off the nucleon (e- N --> e- N(pi)) in the delta(1232)-resonance region. After fixing the three low-energy constants, corresponding to the magnetic (M1), electric (E2), and Coulomb (C2) gammaNdelta couplings, our calculation provides a prediction for the momentum transfer and pion-mass dependence of th...
متن کاملbaryon-baryon interactions in chiral effective field theory
We have constructed the leading order strangeness S = −1,−2 baryon-baryon 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 potential, derived using SU(3) f symmetry constraints, contains six independent low-energy coefficients. We have solved a regularized Lippmann-Schwinger...
متن کاملElastic electron–deuteron scattering in chiral effective field theory
We calculate elastic electron–deuteron scattering in a chiral effective field theory approach for few–nucleon systems based on a modified Weinberg power counting. We construct the current operators and the deuteron wave function at next-to-leading order (NLO) simultaneously within a projection formalism. The leading order comprises the impulse approximation of photons coupling to point-like nuc...
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.
