The neutrino–neutrino interaction effects in supernovae: the point of view from the ‘matter’ basis
We consider the Hamiltonian for neutrino oscillations in matter in the case of arbitrary potentials including off-diagonal complex terms.We derive the expressions for the corresponding Hamiltonian in the basis of the instantaneous eigenstates in matter, in terms of quantities one can derive from the flavor basis Hamiltonian and its derivative, …
