Hyperon-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 کاملbaryon-baryon interactions using chiral effective field theory
We derive the leading order strangeness S = −2 baryon-baryon interactions in chiral effective field theory. The potential consists of contact terms without derivatives and of one-pseudoscalar-meson exchanges. The contact terms and the couplings of the pseudoscalar mesons to the baryons are related via SU(3)f symmetry to the S = −1 hyperonnucleon channels. We show that the chiral effective field...
متن کاملStrange two-baryon interactions using 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 کاملQuantum Monte Carlo calculations with chiral effective field theory interactions.
We present the first quantum Monte Carlo (QMC) calculations with chiral effective field theory (EFT) interactions. To achieve this, we remove all sources of nonlocality, which hamper the inclusion in QMC calculations, in nuclear forces to next-to-next-to-leading order. We perform auxiliary-field diffusion Monte Carlo (AFDMC) calculations for the neutron matter energy up to saturation density ba...
