Réunion du GDR Neutrino

Le Groupement de Recherche (GDR2918 CNRS) NEUTRINO fédère les équipes de recherche du CEA et du CNRS travaillant autour de la physique du neutrino que ce soit au niveau expérimental ou théorique.

Le laboratoire APC (Université Paris -Diderot) organise les prochaines réunions plénières du GDR Neutrino. Elles auront lieu le lundi 29 mai 2017 à partir de 14 h et le mardi 30 mai 2017 de 9 h à 18h, dans l’amphithéâtre Turing.

Opportunities in Atmospheric Neutrino Physics

The not-so-small mixing angle theta13 measured at Daya Bay, RENO, and Double Chooz,
stimulated many design activities for next-generation experiments. In this talk, I
will talk about several aspects of the physics potential in atmospheric neutrino
experiment such as ORCA and PINGU, including mass hierarchy and CP measurements.
Their physics potential can be further extended by observing neutrino trident
production with double muon tracks for direct constraint on new physics beyond the

The SoLid experiment

The recent emergence of the Reactor Antineutrino Anomaly has revived the interest in short-baseline experiments probing the disappearance of electron neutrinos and antineutrinos. The SoLid experiment is a reactor project that aims to resolve the anomaly employing a novel detector design. Installed at a very short distance of ∼ 6.0 - 9.0 m from the BR2 research reactor core at SCK·CEN in Belgium, it will be able to scan the allowed parameter region within a year of data taking through the detection of low energy  ̄νe.

A high-resolution CMOS imaging detector for the search of neutrinoless double β decay in 82Se

I will introduce a new technology of detectors for the search of the neutrinoless double β decay of 82Se. Based on the present literature, imaging devices from amorphous 82Se evaporated on a complementary metal-oxide-semiconductor (CMOS) active pixel array are expected to have the energy and spatial resolution to produce two-dimensional images of ionizing tracks of utmost quality, effectively akin to an electronic bubble chamber in the double β decay energy regime.

Chasing the light sterile neutrino: status of the STEREO experiment

The standard three-family neutrino oscillation model is challenged by a number of observations,
such as the reactor antineutrino anomaly (RAA), that can be explained by the existence of sterile
neutrinos at the eV mass scale. The RAA can be tested by comparing antineutrino energy spectra
at different distances from a reactor core, in order to observe possible distortions due to shortbaseline
oscillations toward sterile neutrinos. After a review of the upcoming experiments and

DynHo: A New Trap For Dark Matter?

We investigate a new method to search for keV-scale sterile neutrinos that could account for Dark Matter. Neutrinos trapped in our galaxy could be captured on stable 163Dy if their mass is greater than 2.83 keV. Two experimental realizations are studied, an integral counting of 163Ho atoms in dysprosium-rich ores and a real-time measurement of the emerging electron spectrum in a dysprosium-based detector. The capture rates are compared to the solar neutrino and radioactive backgrounds.

Neutrinos Physics At Accelerator Driven Subcritical Systems

Accelerator Driven System (ADS) subcritical reactors are being developed around the world, to produce energy and, at the same time, to provide an efficient way to dispose of and to recycle nuclear waste. Spent nuclear fuel, by itself, cannot sustain a chain reaction; however, in ADS reactors the additional neutrons required to sustain the reaction will be supplied by a high-intensity accelerator. In China the C-ADS collaboration is working on the research and development of such an accelerator, starting with a low-energy beam and increasing the energy up to 1.5 GeV.
