2. Axion emission from strange matter in core-collapse SNe

Mael Cavan (Lapth / USMB)

The duration of the neutrino burst from the supernova event SN 1987A is known to be sensitive to exotic sources of cooling, such as axions radiated from the dense and hot hadronic matter thought to constitute the inner core of the supernova. We perform the first quantitative study of the role of hadronic matter beyond the first generation -- in particular strange matter. We do so by...

62. Confront resonant s-wave dark matter to cosmological and astrophysical constraints

Margaux JOMAIN (LAPTh)

25/11/2024 17:00

There are strong cosmological and astrophysical constraints for thermal dark matter below the GeV scale: CMB excludes s-channel annihilation cross-sections for thermal dark matter below 10 GeV. What kind of special properties dark matter should have to evade such strong constraints ?
Resonant annihilation is one possibility.
First, I will explain the effects of resonances on the formation of...

51. Electric dipole response of sd-shell nuclei within the Large-Scale Shell Model approach

Oscar Le Noan (IPHC - Groupe Théorie)

25/11/2024 17:30

Photo-nuclear reaction rates provide key inputs to various applications of nuclear physics and consist fundamental probes of nuclear structure, from single particle to collective excitations, revealing nature of complicated nucleonic correlations. Among the excitations of nuclei due to the external field, the E1 dipole response is of particular interest. In this talk, I will discuss recent...
