Seminar ICAP


The ICAP seminar (for "Initiative in Cosmology and AstroParticle Physics") is a monthly meeting that takes place on the last Thursday of the month from 2:00 pm to 4:00 pm, in order to discuss recent results and current works in the fields of particle physics and cosmology. Anyone is welcome and can suggest subjects of interest by contacting the organizers. Presentations are limited to 20 minutes, and are informal in order to foster scientific discussion.
The seminar is co-organized by Benjamin Wandelt, Marco Cirelli (Laboratoire de Physique Théorique et Hautes Énergie, Sorbonne Université), Cédric Deffayet (Ecole Normale Supérieure), Dmitri Semikoz (Laboratoire Astroparticules et Cosmologie, Université Paris-Cité). It is partly funded by the Fédération de Recherche sur les Interactions Fondamentales (FRIF), and the Initiative Physique des Infinis (IPI), of the Alliance Sorbonne Université.
