Extended Dualization: a method for the Bosonization of Anomalous Fermion Systems in Arbitrary Dimension
José Luis Cortés, Elena Rivas, Luis Velázquez
The technique of extended dualization developed in this paper is used to bosonize quantized fermion systems in arbitrary dimension in the low energy regime. In its original (mi…
Phase Diagram of An SU(2)xSU(2) Scalar-Fermion Model with Massless Decoupled Doublers
J. L. Alonso, F. Lesmes, E. Rivas +1
We present the phase structure of the chiral SU(2)xSU(2) scalar-fermion model on the lattice using the Zaragoza proposal for chiral fermions. The numerical result agrees with an an…
Phase Diagram of a Lattice Scalar-Fermion Model Using the Zaragoza Fermions
J. L. Alonso, Ph. Boucaud, F. Lesmes +1
We present a calculation of the phase diagram of a chiral Yukawa model with massless decoupled doublers, using a saddle point approach, both for small and larg…
The S, U and Δρparameters in the Zaragoza proposal for lattice chiral gauge fermions
Jose Luis Alonso, Philippe Boucaud, Jose Luis Cortes +2
Using the Zaragoza proposal for lattice chiral gauge fermions, the S, U and Δρparameters have been calculated at one loop. It is shown that the continuum values for these quantitie…
On the Eichten--Preskill Proposal for Lattice Chiral Gauge Theories
M. F. L. Golterman, D. N. Petcher, E. Rivas
We have studied the Eichten--Preskill proposal for constructing lattice chiral gauge theories using both strong and weak coupling methods. The results indicate that this proposal i…
Absence of Chiral Fermions in the Eichten--Preskill Model
Maarten Golterman, Don Petcher, Elena Rivas
The model proposed by Eichten and Preskill for obtaining theories with chiral fermions from the lattice is shown to undergo spontaneous symmetry breaking. In addition, the fermions…
