SU(2) Higher-order effective quark interactions from polarization
Higher order quark effective interactions are found for SU(2) flavor by departing from a non-local quark–quark interaction. By integrating out a component of the quark field, the determinant is expanded in chirally symmetric and symmetry breaking effective interactions up to the fifth order in the q...
