in Dimensional Regularization: a Novel Approach
Ruggero Ferrari
A new Dimensional Regularization of is proposed. Cyclicity and Lorentz covariance are enforced. The extension to generic dimension is based on the integral representation of…
On effective Chern-Simons Term induced by a Local CPT-Violating Coupling using in Dimensional Regularization
Ruggero Ferrari, Mario Raciti
We resume a long-standing, yet not forgotten, debate on whether a Chern-Simons birefringence can be generated by a local term in the Lagrangian (where are c…
Managing in Dimensional Regularization II: the Trace with more
Ruggero Ferrari
In the present paper we evaluate the anomaly for the abelian axial current in a non abelian chiral gauge theory, by using dimensional regularization. This amount to formulate a pro…
Managing gamma_5 in Dimensional Regularization and ABJ Anomaly
Ruggero Ferrari
An integral representation is proposed for the trace involving gamma_5 in dimensional regularization. Lorentz covariance is preserved. ABJ anomaly naturally follows. The Local Func…
On the Spectrum of Lattice Massive SU(2) Yang-Mills
Ruggero Ferrari
On the basis of extended simulations we provide some results concerning the spectrum of Massive SU(2) Yang-Mills on the lattice. We study the "time" correlator of local gauge invar…
Nonlinear Realization of the SU(5) Georgi-Glashow Model
Daniele Bettinelli, Ruggero Ferrari, Alessandro Sanzeni
The formulation of a grand unified field theory based on the nonlinearly realized SU(5) gauge group is presented. The tree-level action is constructed by requiring invariance under…
