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…
Axial current in QED and semi-naive dimensional renormalization
M. Pernici, M. Raciti
We renormalize at two loops the axial current and in massless QED, using the recently proposed semi-naive dimensional renormalization scheme. We show that the results…
Dimensional renormalization of Yukawa theories wia Wilsonian methods
M. Pernici, M. Raciti, F. Riva
In the 't Hooft-Veltman dimensional regularization scheme it is necessary to introduce finite counterterms to satisfy chiral Ward identities. It is a non-trivial task to evaluate t…
Wilsonian Flow and Mass-Independent Renormalization
M. Pernici, M. Raciti
We derive the Gell-Mann and Low renormalization group equation in the Wilsonian approach to renormalization of massless in four dimensions, as a particular case of a non-lin…
Hard-Soft Renormalization and the Exact Renormalization Group
M. Pernici, M. Raciti, F. Riva
The Wilsonian exact renormalization group gives a natural framework in which ultraviolet and infrared divergences can be treated separately. In massless QED we introduce, as the on…
Renormalization of Matter Field Theories on the Lattice and the Flow Equation
M. Pernici, M. Raciti, F. Riva
We give a new proof of the renormalizability of a class of matter field theories on a space-time lattice; in particular we consider and massive Yukawa theories with Wilson fe…
