Description

The European COST Action CA21106 "Cosmic WISPers in the Dark Universe: Theory, astrophysics and experiments" is an initiative funded by the COST Association, whose goal is to study axions and other very weakly interacting slim  particles (WISPs) emerging 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 COST Action CA21106 2nd Training School will be held in Ljubljana (Slovenia). 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.

      ALPs coupled to nucleons shining into photons 10m

      In this talk I will explore the phenomenology of Axion-Like Particles (ALPs) coupled to nucleons. I will argue that these couplings must descend from a high-energy theory where ALPs are coupled to both gluons and quarks, which could naturally induce a low-energy coupling to photons. In this scenario, I will discuss the low-energy phenomenology for these ALPs, focusing on their production in core-collapse Supernovae. In particular, the induced photon coupling allows ALPs with masses $m_a \gtrsim 1\,$ MeV to efficiently decay into photon pairs. Then, I will show how the related astrophysical observables can severely constrain the ALP parameter space, enlarging the region ruled out by the usual SN cooling bound.
