The Most General Propagator in Quantum Field Theory
Luca Fabbri, Rodolfo José Bueno Rogerio
One of the most important mathematical tools necessary for Quantum Field Theory calculations is the field propagator. Applications are always done in terms of plane waves and altho…
Non-Causal Propagation for Higher-Order Interactions of Torsion with Spinor Fields
Luca Fabbri
We consider field equations of spinors with torsional interactions having higher-order dimension: by applying the Velo-Zwanziger method, we obtain that it is always possible to fin…
Torsion Axial Vector and Yvon-Takabayashi Angle: Zitterbewegung, Chirality and all that
Luca Fabbri, Roldao da Rocha
We consider propagating torsion as a completion of gravitation in order to describe the dynamics of curved-twisted space-times filled with Dirac spinorial fields; we discuss intere…
Unveiling a spinor field classification with non-Abelian gauge symmetries
Luca Fabbri, Roldao da Rocha
A spinor fields classification with non-Abelian gauge symmetries is introduced, generalizing the the U(1) gauge symmetries-based Lounesto's classification. Here, a more general cla…
A simple assessment on the hierarchy problem
Luca Fabbri
We consider the simplest extension of the standard model, where torsion couples to spinor as well as to scalar fields, and in which the cosmological constant problem is solved.
From Extended Gravity with Torsion-Spin Coupling to Running Constant for Weak-Leptonic Forces
Luca Fabbri
In this paper we show how in the most natural extension of gravity with torsion, fermion fields are endowed with running coupling in spinorial interaction, that are shown to reprod…
