Chiral oscillations in finite time quantum field theory
Massimo Blasone, Francesco Giacosa, Luca Smaldone +1
We demonstrate how chiral oscillations of a massive Dirac field can be described within quantum field theory using a finite-time interaction picture approach, where the mass term i…

Flavor neutrinos as unstable particles: an interaction picture view
M. Blasone, F. Giacosa, L. Smaldone +1
This paper reviews the similarities in the behavior of unstable particles and oscillating neutrinos using perturbation theory within the interaction picture of quantum field theory…
