SUMMARY:Resonant dark forces and small scale structure
DESCRIPTION:Featuring Sean Tulin\, University of Michigan\n\nPart of the HE
	T Seminar Series.\n\nAbstract: A dark force can impact the cosmological his
	tory of dark matter (DM)\, both explaining the observed cores in dwarf gala
	xies and setting the DM relic density through annihilation to dark force bo
	sons.  For GeV-TeV DM mass\, DM self-scattering in dwarf galaxies exhi
	bits quantum mechanical resonances\, analogous to Sommerfeld enhancements f
	or annihilation.  We show that a simple model of DM with a dark force 
	can accommodate all astrophysical bounds on self-interactions in haloes and
	 explain the observed relic density\, all through a single coupling constan
	t.
