The Diffuse Supernova Neutrino Background (DSNB) is the neutrino signal formed by all past core-collapse Supernovae (SNe) in the Universe. Never detected, its expected flux and spectrum can be predicted based on astrophysical observations of star formation and supernova rates and sophisticated simulations of core-collapse events and the accompanying neutrino emission.
With SK-Gd taking data and JUNO about to come online, there are currently two experiments that have a realistic chance for a first observation of the DSNB signal before 2030. What is more, there are several further experiments (HK, DUNE, DARWIN etc.) on the horizon that will extend the sensitivity and allow us to explore the spectra of different neutrino flavors.
In light of the imminent arrival of first DSNB data, this workshop aims to brings together theorists and experimentalists to investigate several key questions:
- What is the predicted signal level, what are the astrophysical and theory inputs?
- What are the prospects for the first detection of the DSNB in SK-Gd and JUNO?
- What can we hope to learn from the first data?
- What perspectives are there for further measurements by future experiments?
The registration deadline is May 29, 2024.
