Description
Neutrino flavor is expected to undergo fast and large oscillations due to collective effects in neutrino-dense environments, where neutrino-neutrino interactions are at play. While a quantum kinetics treatment is known to predict a smaller effect from non-forward scattering in such interactions compared to forward scattering (i.e., flavor swaps), this hierarchy has not yet been clearly established in general. I will discuss how we can model both of these contributions to neutrino interactions directly from low-energy effective field theory and compare the relative importance of forward and non-forward scattering terms.
