SUMMARY:The Search for Relic Neutrinos
DESCRIPTION:Featuring Dr. Mariangela Lisanti\, Princeton University\nHosted
	 by: Tulika Bose\n\nPart of the HEE Seminar Series.\n\nAbstract: \nThe cosm
	ic neutrino background\, produced about one second after the Big Bang\, per
	meates the Universe today.  New technological advancements make neutrino ca
	pture on beta-decaying nuclei \na clear path forward towards the detection 
	of these relic neutrinos.\nWe show that gravitational focusing by the Sun c
	auses the expected neutrino capture rate to modulate annually. The amplitud
	e and phase of the modulation depend on the phase-space distribution of the
	 local neutrino background\, which is perturbed by structure formation.  In
	 addition\, we show that relic neutrino observatories may measure anisotrop
	ies in the cosmic neutrino velocity and spin distributions by polarizing th
	e tritium targets.  The polarized-target measurements may also constrain no
	n-standard neutrino interactions that would induce larger anisotropies and 
	help discriminate between Majorana versus Dirac neutrinos.
