Hi guys,
I was wondering if anyone knows of a good source/paper that I can find online that details how to derive the MSW Hamiltonian from a field-theoretic approach, or from an effective field theory approach or anything like that? Every time I study the MSW effect, the Hamiltonian ##\sqrt{2}G_F n_e \left|\nu_e\right>\left<\nu_e\right|## is just given. I know it comes from the electron neutrinos being the only flavor of neutrinos which have charged current interactions with electrons, while the neutral current interactions are flavor blind, but I don't know any more details other than that. Thanks.
