DESCRIPTION:Speakers: Yannis Georis (IPMU)\n\nThe effective number of neut
 rinos\, Neff\, is a key parameter in the standard Lambda-CDM cosmology\, p
 arametrising the amount of radiation in the early universe and therefore a
 cting as a crucial probe of light and feebly interacting hidden sectors. I
 n this seminar\, I will briefly review standard effects that impact the th
 eoretical prediction for Neff in the Standard Model. I will then discuss r
 ecent works studying whether higher-order QED corrections can significantl
 y impact this prediction.\n\nhttps://indico.zdv.uni-mainz.de/event/193/
