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<br>
\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<br>
\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<br>
\nto occur.  Similarly\, the conditions of the innermost\, neu
 trino-heated supernova ejecta would also be affected and I illustrate 
 possible effects with nucleosynthesis <br>
\ncalculations based on a 3
 D supernova model.  <br>
