摘要：A lattice action for naive fermions is presented which, near a weak-coupling phase transition,
can have small massses for the 8 doublers of one chirality while rendering those of opposite
chirality much heavier than R. The action is ultra-local and obeys all fundamental principles
including exact gauge invariance when gauge fields are included. Analytical calculations have
been done for models with both U(1) and SU(2) global symmetries. The same analysis is in
reasonable agreement with old simulation results in the Smit-Swift model where the mass of
the lightest unwanted doubler remains below < f >R near the weak-coupling transition. The
possible relevance of my model toward a non-perturbative formulation of the Standard Model is
also discussed.
