SUMMARY:Neutrino Quantum Kinetics and the Early Universe\, NPAC (Nucle
 ar/Particle/Astro/Cosmo) Forum\, Evan Grohs \, University of Michigan
DESCRIPTION: The laboratory of the early universe provides a setting f
 or testing Beyond Standard Model (BSM) physics in the particle and cos
 mological sectors.  Any BSM physics in operation at early times may pr
 oduce slight deviations on the primordial element abundances and cosmi
 c microwave background observables predicted within the standard cosmo
 logy.  The identification and characterization of such BSM signatures 
 require a precise treatment of the neutrino energy and flavor wave fun
 ctions during the time of Big Bang Nucleosynthesis (BBN) using the Qua
 ntum Kinetic Equations (QKEs).  I will review some of the work done on
  characterizing BBN with a Boltzmann-energy-transport approach\, as we
 ll as ongoing work towards a full QKE treatment with neutrino oscillat
 ions and collisions.  A QKE treatment of early-universe neutrino physi
 cs will greatly assist observers and theorists as the next generation 
 cosmological experiments come on line in the near future.
