Neutrino Oscillations Above A Black Hole Accretion Disk

Black hole accretion disks can occur in certain core collapse supernovae as well as in the mergers of compact objects. This environment produces a strong flux of electron neutrinos and electron antineutrinos. These neutrinos are instrumental in determining the type of elements produced in disk outflows. In the context of this scenario, using the single angle approximation and a constant temperature disk, we report on calculations of neutrino flavor transformation driven by neutrino self interactions. We comment on the impact on element synthesis.
