Equivalent hyperon-nucleon interactions in low-momentum space

Year: 2007

Type: article

Abstract: Equivalent interactions in a low-momentum space for the $\ensuremath{\Lambda}N,\ensuremath{\Sigma}N$, and $\ensuremath{\Xi}N$ interactions are calculated, using the ${\mathrm{SU}}_{6}$ 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 $\mathit{YN}$ interactions.
