COSMICWISPers

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 objective of  the CA21106 2nd General Meeting is to review the status of the activities performed by the different Working Groups and to discuss the further directions of investigations.   The goal of the 2nd Training School is to continue 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.

The first General Meeting of the COSMIC WISPers Action [https://agenda.infn.it/event/34125/] took place in Bari (Italy) from 5th to 8th  September 2023. The objective of the meeting was to review the status of the activities performed by the different Working Groups and to discuss the further directions of investigations. There were plenary sessions and 4 parallel sessions corresponding to the different Working Groups:
   • WG1: Theory and Model Building 
   • WG2: Dark Matter and Cosmology 
   • WG3: Astrophysics 
   • WG4: Direct Searches

After the General Meeting, the COST Action CA21106 1st Training School was held in Lecce (Italy) (https://agenda.infn.it/event/34190/) from 11st to 14th September 2023. The goal was 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.
There were four lectures on different topics corresponding to the Working Groups 1—4 and several students talks.
