Perturbative and nonperturbative aspects of neutrino oscillations in quantum field theory

Abstract

In this work, we present a comprehensive and pedagogical review of two quantum field theoretical approaches to neutrino flavor mixing and oscillations: the non-perturbative flavor Fock space formalism and the perturbative interaction picture framework.
