Exploration of in-medium hyperon-nucleon interactions
نویسندگان
چکیده
The study focuses on exploring the changes in hyperon-baryon interaction at various nuclear densities. This approach starts by building a vacuum hyperon-nucleon model based Boson -Exchange maintaining SU(3) flavor symmetry. Bethe-Goldstone equation is then explored to investigate medium properties over bare interaction. A detailed investigation of density dependence revealed clear low energy parameters with variation shown for different strangeness channels.

Induced Hyperon-Nucleon-Nucleon Interactions and the Hyperon Puzzle.
We present the first ab initio calculations for p-shell hypernuclei including hyperon-nucleon-nucleon (YNN) contributions induced by a similarity renormalization group transformation of the initial hyperon-nucleon interaction. The transformation including the YNN terms conserves the spectrum of the Hamiltonian while drastically improving model-space convergence of the importance-truncated no-co...
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...

Twoand three-body Y-N potentials including the rescattering corrections are calculated by using Miyazawa's method. The Y-N systems are treated by the two-channel formalism in the case of T=1/2: The one is the channel of the I-N system and the other is of the A-N system. Then the potential is defined as the 2 X 2 matrix form. The three-body force vanishes, in which no direct two-nucleon interact...
متن کاملHyperon - nucleon interactions in the pp → K + Λ p reaction
We present calculations of the invariant mass spectra of the Λp system for the exclusive pp → K + Λp reaction with the aim of studying the final state interactions between the Λ-hyperon and the proton. The reaction is described within a meson exchange framework and the final state Λp interactions are incorporated through an off-shell T-matrix for the Λp → Λp scattering, constructed using the av...
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.
