Large-$N_c$ operator analysis of hyperon-nucleon interactions in SU(3) chiral effective field theory

Xuyang Liu, Viroj Limkaisang, Daris Samart +1

We study octet-octet baryon ($J^P={\frac{1}{2}}^{+}$) contact interactions in SU(3) chiral effective field theory by using large-$N_c$ operator analysis. Applying the $1/N_c…
