SUMMARY:Potential Effects of Fast Neutrino Flavor Transformations on N
eutrino-Driven Wind and Supernova Nucleosynthesis\, Network in Neutrin
os\, Nuclear Astrophysics\, and Symmetries (N3AS) Seminar\, Andre Sier
verding \, University of Minnesota
DESCRIPTION:Recently\, the possibility that fast neutrino flavor trans
formations may occur very close to the core of a collapsing massive st
ar has received a lot of
\nattention. Such transformations would
affect the conditions of the wind driven by the intense neutrino emiss
ion from a proto-neutron star (PNS) where nuclei
\nheavier than Fe
can be produced. We show that flavor transformations would lead to m
ore proton-rich outflows and more favorable conditions for a nu-p proc
ess
\nto occur. Similarly\, the conditions of the innermost\, neu
trino-heated supernova ejecta would also be affected and I illustrate
possible effects with nucleosynthesis
\ncalculations based on a 3
D supernova model.
