Anomalies for Nonlocal Dirac Operators
E. Ruiz Arriola, L. L. Salcedo
The anomalies of a very general class of non local Dirac operators are computed using the -function definition of the fermionic determinant and an asymmetric version of the Wign…
Hadron Structure Functions in a Chiral Quark Model
Leonard Gamberg, Herbert Weigel
We present a consistent regularization procedure for calculating hadron structure functions in a bosonized chiral quark model. We find that the Pauli-Villars regularization scheme…
On the Structure Functions of Mesons and Baryons in a Chiral Quark Model
E. Ruiz Arriola
This research summarizes work done by myself (Nucl.Phys.{\bf A641} (1998)461), or in collaboration with R. M. Davidson (Phys.Lett.{\bf B348}(1995)163) and H. Weigel and L. Gamberg…
Bethe-Salpeter Approach for Unitarized Chiral Perturbation Theory
J. Nieves, E. Ruiz Arriola
The Bethe-Salpeter equation restores exact elastic unitarity in the channel by summing up an infinite set of chiral loops. We use this equation to show how a chiral expansion…
Error estimates for pi-pi scattering threshold parameters in Chiral Perturbation Theory to two loops
J. Nieves, E. Ruiz Arriola
Using the analysis of ChPT to two loops, we perform an error analysis of the threshold and low energy parameters, based on the uncertainties for the one loop low energy parameters…
Hadron Structure Functions in a Chiral Quark Model: Regularization, Scaling and Sum Rules
H. Weigel, E. Ruiz Arriola, L. Gamberg
We provide a consistent regularization procedure for calculating hadron structure functions in a chiral quark model. The structure functions are extracted from the absorptive part…
