Large-Nc operator analysis of hyperon–nucleon interactions in SU(3) chiral effective field theory
We study octet–octet baryon (JP=12+) contact interactions in SU(3) chiral effective field theory by using large-Nc operator analysis. By applying the 1/Nc expansion of the Hartree Hamiltonian, we find 15 operators in the octet–octet baryon potential where 4 operators for the leading order (LO) and 1...
