SUMMARY:Reconciling supersymmetry with leptogenesis by the strong CP proble
	m and observations
DESCRIPTION:Featuring Jasper Hasenkamp\, DESY\n\nPart of the HET Seminar Se
	ries.\n\nAbstract:A consistent cosmology has to explain the observed matter
	 composition of the Universe and should enable solutions to all proble
	ms of the standard model. To this end\, we investigate solutions to th
	e gravitino  problem of leptogenesis as origin of matter and at the sa
	me time implement the Peccei-Quinn mechanism as solution to the strong
	 CP problem. In this overall picture a consistent cosmology appears--m
	aybe counter-intuitively-- easier to achieve than particular solutions
	 to  each subproblem. Problems often even turn out as fortunes. More&n
	bsp;importantly\, such scenarios are\, in addition\, observable in the cosm
	ic microwave background and the gravitational wave background from inf
	lation.
