Title: Comparative study of hyperon-nucleon interactions in a quark model and in chiral effective field theory by low-momentum equivalent interactions and G matrices

Abstract

Hyperon-nucleons interactions constructed by two frameworks, the Kyoto-Niigata SU{sub 6} quark model and the chiral effective field theory, are compared by investigating equivalent interactions in a low-momentum space and, in addition, by calculating hyperon single-particle potentials in the lowest-order Brueckner theory in symmetric nuclear matter. Two descriptions are shown to give similar matrix elements in most channels after renormalizing high momentum components. Although the range of the {Lambda}N interaction is different in two potentials, the {Lambda} single-particle potential in nuclear matter is very similar. The {Sigma}-nucleus and XI-nucleus potentials are also found to be similar. These predictions are to be confronted with forthcoming experimental data.
