Title: Equivalent hyperon-nucleon interactions in low-momentum space

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.
