Latest Results of the Diffuse Supernova Neutrino Background Search in Gadolinium-loaded Super-Kamiokande

The Diffuse Supernova Neutrino Background (DSNB) is the collection of neutrinos emitted from all past core-collapse supernovae, and it has yet to be detected experimentally. An observation of the DSNB can probe the star formation history of the universe, the fraction of black hole-forming supernovae, and even novel neutrino physics phenomena. At present, the Super-Kamiokande (SK) water Cherenkov detector is the most sensitive experiment to detect the DSNB.

International Workshop on Multi-messenger Tomography of the Earth

The second Workshop on Multi-Messenger Tomography of the Earth will be held from the 4th to 7th of July, 2023 at Université Paris Cité in Paris (France), jointly organized by Laboratoire AstroParticule et Cosmologie and Institut de Physique du Globe de Paris.
The aim of the workshop is to bring together geoscientists and neutrino physicists to explore new pathways of combining their methodological approaches and data towards a multi-messenger tomography of the Earth.

Title: (Almost) 10 years of Higgs boson: from the discovery to the precision era

Abstract:

First signs of the Glashow resonance from an astrophysical (anti)neutrino

The Glashow resonance describes the resonant formation of an on-mass W- boson via the scattering of an electron antineutrino and an electron, a process first predicted in 1959. In the electron rest frame, the requisite neutrino energy of 6.3 PeV lies beyond the reach of terrestrial accelerators. However, the discovery of a diffuse flux of astrophysical neutrinos by IceCube gave rise to the possibility of detecting the resonance via high-energy (anti)neutrinos from outer space.

Searches for High-Energy Neutrinos from the Sun

Abstract: While the Sun has already proved a fruitful laboratory for neutrino physics, high-energy solar neutrinos may continue to provide insight. For example, current-generation neutrino telescopes have searched for an excess of neutrinos from the Sun’s direction as evidence of annihilating weakly interacting massive particles (WIMPs) at energies from ~0.1 GeV to 10^4 GeV. Detection of these neutrinos would be a smoking-gun signature of WIMPs since backgrounds from the Sun are well-understood.

Large TPCs for low-energy rare event detection

Cher(e)s Collègues, dear Colleagues (English version below),

Nous sommes heureux de vous annoncer que le 10ème Symposium on Large TPCs for Low-Energy Rare Events se tiendra :
du 15 au 17 décembre 2021 à l'Université de Paris, amphithéâtre Buffon, 15 rue Hélène Brion à Paris.

Comme lors des précédentes conférences de cette série, la physique et les détecteurs d'événements rares (matière noire, double désintégration bêta, interactions neutrinos, Axions) seront abordés.
