Chiral Symmetry and Vertex Symmetry in the Extended Moeller-Rosenfeld Model
Abstract
Description
Vertex symmetry for interacting fermions will be shown to lead to a Lagrangian exhibiting $SU(2N)_W$ invariance associated with the subgroup $SU(2N)_q \times SU(2N)_{\bar{q}}$ generated by $C$-odd and $C$-even spin operators. Approximate $SU(6)_W$ vertex symmetry as well as chiral invariance will then be shown to follow from a principle of maximum smoothness (Möller-Rosenfeld) of the bound state quark wave function.
