AbstractFor neutrinos streaming from a supernova core, dense matter suppresses self-induced flavor transformations if the electron density n(e) significantly exceeds the neutrino density n(nu) in the conversion region. If n(e) is comparable to n(nu), one finds multiangle decoherence, whereas the standard self-induced transformation behavior requires that in the transformation region n(nu) is safely above n(e). This condition need not be satisfied in the early phase after the supernova core bounce. Our new multiangle effect is a subtle consequence of neutrinos traveling on different trajectories when streaming from a source that is not pointlike.
