NN,NΔCouplings and the Quark Model
Thomas R. Hemmert, Barry R. Holstein, Nimai C. Mukhopadhyay
Abstract
We examine mass-corrected SU(6) symmetry predictions in the quark model relating vector, axial-vector and strong NN and NΔcouplings, and demonstrate that the experimental NΔvalue is significantly higher than predicted in each case. Nevertheless the Goldberger-Treiman relation is satisfied in both sectors. Possible origins of the discrepancy of the quark model predictions with experiment are discussed.
