SUMMARY:Revisiting Quantum Field Theory in non-integer dimensions
DESCRIPTION:Featuring Slava Rychkov\, CERN\n\nPart of the HET Seminar Serie
	s.\n\nAbstract:\nEveryone knows that the Wilson-Fisher fixed point is suppo
	sed to exist continuously for any D between 2 and 4\, \nbut what is the mea
	ning of QFT in non-integer dimensions? This question is rarely asked and th
	e "shut up and calculate" attitude prevails. We will describe a few recent 
	exercises in QFT in non-integer dimensions\, connecting with the epsilon-ex
	pansion\, conformal bootstrap\, and truncated conformal space approach to m
	assive theories. A tentative conclusion is that QFT in non-integer dimensio
	ns makes sense \nalso non-perturbatively\, although to do it properly one h
	as to face some unexpected issues such as the lack of unitarity.
