SUMMARY:Higgscitement: cosmological dynamics of fine-tuning
DESCRIPTION:Featuring JiJi Fan\, Brown University\n\nPart of the HET Semina
	r Series.\n\nThe Higgs potential appears to be fine-tuned\, hence very sens
	itive to values of other scalar fields that couple to the Higgs. I will sho
	w that this feature can lead to a new epoch in the early universe featuring
	 violent dynamics coupling the Higgs to a scalar modulus. The oscillating m
	odulus drives tachyonic Higgs particle production. We find a simple paramet
	ric understanding of when this process can lead to rapid modulus fragmentat
	ion\, resulting in gravitational wave production. A nontrivial equation-of-
	state arising from the nonlinear dynamics also affects the time elapsed fro
	m inflation to the CMB\, influencing fits of inflationary models. Supersymm
	etric theories automatically contain useful ingredients for this picture.
