1st General Meeting of COST Action COSMIC WISPers (CA21106)

5 Sept 2023, 08:15 → 8 Sept 2023, 19:00 Europe/Rome

Aula Alessandro Leogrande ( Centro Polifunzionale Studenti (ex Palazzo delle Poste e Telegrafi), Bari (Italy).)

Alessandro Mirizzi

Axions and other very weakly interacting slim (m<GeV) particles (WISPs) are easily accommodated in several extensions of the Standard Model of Particle Physics. Searches for WISPs are strongly motivated by our attempts to understand the nature of the dark matter and puzzling astrophysical and particle physics observations. 

 The aim of the COST Action COSMIC WISPers (CA21106) is to coordinate and support WISPs searches in a synergic way at the boundary between particle physics, astrophysics and cosmology. 

The CA21106 1st General Meeting will be held in Bari (Italy).  The objective of  the meeting is to review the status of the activities performed by the different Working Groups and to discuss the further directions of investigations. 

The Management Committee Meeting will take place in the afternoon of Friday 8th September.
