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 CA21106 3rd General Meeting will be held in Bulgaria. 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 COST Action CA21106 3rd Training School will be held in Annecy (France) at the LAPTh, a world-class research laboratory just 40 km away from CERN.

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 at early-career postdocs.

COSMIC WISPers (CA21106) is a COST Action [https://www.cost.eu/actions/CA21106/, https://cosmicwispers.eu/] focusing on very Weakly Interacting Slim Particles (WISPs). The aim of the COST Action COSMIC WISPers is to coordinate and support WISPs searches in a synergic way at the boundary between particle physics, astrophysics and cosmology.

The CA21106 2nd General Meeting [https://agenda.infn.it/event/39939/] took place in Istanbul (Turkey) from 3rd to 6th of September 2024. 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

Before the General Meeting, the COST Action CA21106 2nd Training School [https://indico.ijs.si/event/1825/] was held in Ljubljana (Slovenia) from 10th to 14th of June 2024. 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. For this purpose, there were lectures from experts on different topics of WISPs physics and several students and early-career postdocs talks.

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.
