Abstract

Equivalent interactions in a low-momentum space for the {lambda}N,{sigma}N, and {xi}N interactions are calculated, using the SU{sub 6} quark model potential as well as the Nijmegen OBEP model as the input bare interaction. Because the two-body scattering data has not been accumulated sufficiently to determine the hyperon-nucleon interactions unambiguously, the construction of the potential even in low-energy regions has to rely on a theoretical model. The equivalent interaction after removing high-momentum components is still model dependent. Because this model dependence reflects the character of the underlying potential model, it is instructive for better understanding of baryon-baryon interactions in the strangeness sector to study the low-momentum space YN interactions.

Low-momentum hyperon-nucleon interactions

Journal Article Schaefer, B -J ; Wagner, M ; Wambach, J ; ... - Physical Review. C, Nuclear Physics

We present a first exploratory study for hyperon-nucleon interactions using renormalization group techniques. The effective two-body low-momentum potential V{sub lowk} is obtained by integrating out the high-momentum components from realistic Nijmegen YN potentials. A T-matrix equivalence approach is employed, so that the low-energy phase shifts are reproduced by V{sub lowk} up to a momentum scale {lambda}{approx}500 MeV. Although the various bare Nijmegen models differ somewhat from each other, the corresponding V{sub lowk} interactions show convergence in some channels, suggesting a possible model-independent YN interaction at low momenta.

Extended-soft-core baryon-baryon model. II. Hyperon-nucleon interaction

Journal Article Rijken, Th A ; Yamamoto, Y ; Physics Section, Tsuru University, Tsuru, Yamanashi 402-8555 - Physical Review. C, Nuclear Physics

The YN results are presented from the extended soft-core (ESC) interactions. They consist of local and nonlocal potentials because of (i) one-boson exchanges (OBE), which are the members of nonets of pseudoscalar, vector, scalar, and axial mesons; (ii) diffractive exchanges; (iii) two-pseudoscalar exchange; and (iv) meson-pair exchange (MPE). Both the OBE and pair vertices are regulated by Gaussian form factors producing potentials with a soft behavior near the origin. The assignment of the cutoff masses for the baryon-baryon-meson (BBM) vertices is dependent on the SU(3) classification of the exchanged mesons for OBE and a similar scheme for MPE.

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

Journal Article Kohno, M - Physical Review. C, Nuclear Physics

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 bemore »« less

Soft-core hyperon-nucleon potentials.

Journal Article Rijken, T A ; Stoks, V G. J. ; Yamamoto, Y ; ... - Phys. Rev. C

A new Nijmegen soft-core OBE potential model is presented for the low-energy YN interactions. Besides the results for the fit to the scattering data, which largely defines the model, we also present some applications to hypernuclear systems using the G-matrix method. The potentials are generated by the exchange of nonets of pseudoscalar, vector, and scalar mesons. As is standard in the Nijmegen soft-core models, we also include the J=0 contributions from the tensor f{sub 2},f{sub 2}',a{sub 2}, and pomeron Regge trajectories, and use Gaussian form factors to guarantee that the potentials have a soft behavior near the origin.

Hyperon-nucleon scattering

Conference Rijken, T A ; Maessen, P M.M. ; de Swart, J J - AIP Conference Proceedings (American Institute of Physics); (United States)

The YN-scattering low energy data are analyzed from the perspectives of the recently published Nijmegen soft-core Hyperon-Nucleon potential model. This model is derived from the soft-core Nucleon-Nucleon model using notably SU(3). Differences with the Nijmegen hard-core models D and F are indicated. The predictions of the differential cross section and the {Lambda}-spin observables {ital D}{sub {ital NN}}, {ital D}{sub {ital SS}}, {ital D}{sub {ital SL}}, {ital D}{sub {ital LS}}, and {ital D}{sub {ital LL}}, which could be measured by PILAC, are given for {ital p}{sub {Lambda}}(lab)=600 MeV/c.
