SUMMARY:An Enhanced Source for Electroweak Baryogenesis
DESCRIPTION:Featuring Christopher Lee\, MIT\n\nPart of the HET Seminar Seri
	es.\n\nAbstract:\nIn electroweak baryogenesis\, baryon-violating sphaleron 
	transitions convert CP-violating densities generated during the electroweak
	 phase transition into baryon number asymmetry. Modern methods to calculate
	 the CP-violating sources rely on quantum Boltzmann equations expanded in p
	owers of gradients of the Higgs vev profile. I show how to power count in g
	radients consistently and thereby uncover a previously unnoticed source for
	 the CP-violating densities and therefore the baryon asymmetry.
