N ∆ Couplings and the Quark Model ∗

We examine mass-corrected SU(6) symmetry predictions in the quark model relating vector, axial-vector and strong NN and N∆ coupling, and demonstrate that the experimental N∆ value is significantly higher than predicted in each case. Nevertheless the GoldbergerTreiman relation is satisfied in both sectors. Possible origins of the discrepancy of the quark model predictions with experiments are discussed.
