4th Training School of COST Action COSMIC WISPers (CA21106)

Jun 17, 2026, 8:15 AM → Jun 20, 2026, 11:20 PM Europe/Athens

Mon Repos Palace (Corfu (Greece))

Alessandro Mirizzi (Istituto Nazionale di Fisica Nucleare), George Zoupanos, Konstantinos Anagnostopoulos

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 COST Action CA21106 4th Training School will be held in Corfu' (Greece). The goal is to start training a generation of young scientists in the interdisciplinary expertise on WISPs, ranging from theoretical and experimental  approaches to multi-messenger astroparticle physics and cosmology. For this purpose, the Training School will offer lectures from experts on different aspects of WISPs physics. The School is aimed at PhD students, as well as early-career postdocs.
