摘要
本文提出了一种对Lambda和Sigma单粒子势的分析，基于在次次下一级次序(NLO)内导出的Y-N相互作用。 employed within the continuous choice for the single-particle potential. The result for the Lambda single-particle potential is comparable to the ones obtained with previous chiral YN interactions up to next-to-leading order (NLO). The Sigma single-particle potential is found weakly attractive, in contrast to earlier weakly repulsive results, reflecting new constraints from the recent J-PARC E40 data on scattering. An estimate of the theoretical uncertainty of the single-particle potentials is provided.
