Comparative study of hyperonnucleon interactions in a quark model and in chiral effective field theory by lowmomentum equivalent interactions and G matrices
Abstract
Hyperonnucleons interactions constructed by two frameworks, the KyotoNiigata SU{sub 6} quark model and the chiral effective field theory, are compared by investigating equivalent interactions in a lowmomentum space and, in addition, by calculating hyperon singleparticle potentials in the lowestorder 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} singleparticle potential in nuclear matter is very similar. The {Sigma}nucleus and XInucleus potentials are also found to be similar. These predictions are to be confronted with forthcoming experimental data.
