Delta-rho in an SU(2) X U(1) chiral Yukawa model
J. L. Alonso, Ph. Boucaud, A. J. van der Sijs
We report on a simulation in progress of an SU(2) X U(1) fermion-Higgs model with two *non-degenerate* fermion doublets. The Zaragoza proposal for chiral lattice fermions is used;…
A class of chiral fermion models
J. L. Alonso, Ph. Boucaud, F. Lesmes +1
We study the relation between the Roma and Zaragoza proposals for chiral fermions on the lattice. The fermion action in the Roma approach is shown to be equivalent to one of the Za…
Roma versus Zaragoza
J. L. Alonso, Ph. Boucaud, F. Lesmes +1
The Roma and Zaragoza actions for chiral fermions on the lattice are shown to be essentially equivalent. The auxiliary fermion fields in the Roma model can be integrated out, and t…
Massless Decoupled Doublers: Chiral Yukawa Models and Chiral Gauge Theories
J. L. Alonso, Ph. Boucaud, J. L. Cortes +2
We present a new method for regularizing chiral theories on the lattice. The arbitrariness in the regularization is used in order to decouple massless replica fermions. A continuum…
