Abstract:
The high temperatures and densities reached in supernova cores constitute an ideal environment to produce and test exotic particles such as axions, axion-like particles, heavy neutral leptons, dark photons, gauge bosons, Majorons, sterile neutrinos and other light dark matter candidates. Besides, these objects are also crucial to test neutrino self-interactions, which cannot be probed otherwise in terrestrial experiments.
The potential signatures from this invisible sectors include an increase in the photon or neutrino flux; effects on the cosmic ray spectrum; the shortening of the neutrino burst duration due to an excessive cooling; the enhancement of the explosion energy released by Type II supernovae; modifications of the neutrino flavour composition; and changes in the standard explosion mechanism which must be carefully explored in self-consistent simulations.
