An SU(2)LxSU(2)R symmetric Yukawa model in the symmetric phase

Creators

Description

The lattice regularized SU(2)LxSU(2)R symmetric scalar fermion model with explicit mirror fermions is investigated in the phase with unbroken symmetry. In the present work numerical Monte Carlo calculations with dynamical fermions are performed on a 43x8 lattice near the expected perturbative Gaussian fixed point. The bare Yukawa coupling of the mirror fermion is fixed at zero. The numerical simulations are supported by lattice perturbation theory. (orig.)
