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…
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…
Instanton-like Contributions to the Dynamics of Yang-Mills Fields on the Twisted Torus
The RTN Collaboration, Garcia Perez, Gonzalez-Arroyo +16
We study lattice gauge theory in small volumes and with twist . We investigate the presence of the periodic instantons of and determine the…
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…
