SUMMARY:Dirac Neutrinos & Spectral Distortions to the Cosmic Neutrino 
 Background\, Network in Neutrinos\, Nuclear Astrophysics\, and Symmetr
 ies (N3AS) Seminar\, Evan Grohs\, NCSU
DESCRIPTION:The neutrino sector in particle physics and cosmology cont
 ains many unanswered questions.  The mechanism which generates neutrin
 o masses still remains a mystery\, and as a result so does the nature 
 of Dirac versus Majorana character.  In addition\, cosmological parame
 ters estimate the energy density of the neutrino background and have l
 ittle to say about the shape of the relic spectra.  In this talk\, I w
 ill focus on two applications of neutrino cosmology: populating Dirac 
 states in the cosmological neutrino background via anomalous magnetic 
 moments\; and leveraging primordial abundances and cosmological parame
 ters to infer neutrino spectral distortions.  Although independent\, b
 oth tracks offer paths forward to investigating the nature of neutrino
 s in cosmology and particle physics.<br>\n<br>\nhttps://berkeley.zoom.
