In the framework of quantum field theory, we analyze the neutrino oscillations in the presence of a torsion background. We consider the Einstein– Cartan theory and we study the cases of constant torsion and of linearly time-dependent torsion.

Abstract
In the framework of quantum field theory, we analyze the neutrino oscillations in the presence of a torsion background. We consider the Einstein– Cartan theory and we study the cases of constant torsion and of linearly time-dependent torsion. We derive new neutrino oscillation formulae which depend on the spin orientation and the CP-asymmetry formula. Experiment such as PTOLEMY which analyzes the cosmological background of neutrino, can provide insights into the effect shown here [1].File in questo prodotto:
