Phase Diagram of a Lattice $S U (2) \times S U (2)$ Scalar-Fermion Model Using the Zaragoza Fermions

arXiv:hep-lat/9311062 · doi:10.1016/0920-5632(94)90473-1

Abstract

We present a calculation of the phase diagram of a $S U (2) \times S U (2)$ chiral Yukawa model with massless decoupled doublers, using a saddle point approach, both for small and large Yukawa coupling. Some preliminary MonteCarlo results are also shown.
