T2K recent results and future prospects

T2K (Tokai to Kamioka) is a long-baseline neutrino oscillation experiment designed to measure (anti-)neutrino flavour oscillations using an off-axis (anti-)neutrino beam. After the measurement of a non-zero value for the last unknown mixing angle, theta13, and the most precise measurement of  theta23, T2K has started a campaign to measure CP violation in the leptonic sector taking data with both neutrino and an anti-neutrino beam.

Multi-messenger astroparticle physics - a theory perspective

I discuss perspectives for modern multi-messenger astroparticle physics
including cosmic rays and neutrinos from the theory point of view.
Examples are the cosmogenic neutrino flux expected from cosmic ray
observations, the possible common origin of the neutrinos and cosmic rays at the
highest energies from the same sources, and the implications
of the neutrinos observed from blazar TXS 0506+056.

Workshop DOUBLE-BETA-DECAY

The Double β Neutrino-less (2β0ν) is a fundamental process expected if neutrinos were Majorana particles; i.e. a neutrino being its own anti-particle. There is wide theoretically motivation behind this hypothesis including vast phenomenology. However, 2β0ν remains experimentally unproved. Therefore, the 2β0ν search is a compelling subject of fundamental neutrino research to establish the most profound nature of neutrinos with major potential consequences to our understanding of the Universe as of today.

The quest for dark matter with liquid argon

Au cours des derniers mois, des expérimentateurs de différentes recherches de la matière noire par l'argon ont uni leurs forces pour réaliser un programme unifié de détection directe de la matière noire, sous l'égide de la Global Argon Dark Matter Collaboration.  Cet effort, dirigé par le prix Nobel Art McDonald de DEAP-3600 et par le professeur Cristiano Galbiati, porte-parole de DarkSide, a également bénéficié des chercheurs de l'APC et du LPNHE parmi les principaux acteurs. 

GDR neutrinos

The NEUTRINO Research Group (GDR) gathers CEA and CNRS research teams working on Neutrino Physics on experimental or theoretical level.

The APC laboratory (University of Paris Diderot) is organizing the next GDR plenary meeting. The sessions will be held in the Turing Amphitheater.

The meeting will start on Monday June 11th at 14:00 and continue on Tuesday June 12th (9:00-18:00). A restricted meeting of the GDR Council (Conseil de Groupement) will be held on Monday morning at 10:30.

Supernova properties and flux reconstruction in water Cherenkov detectors

When the next galactic supernova will occur, present and future detectors -- e.g. Super-Kamiokande, IceCube or JUNO- will hopefully guarantee many neutrino events in many channels of detection. At present, however, huge uncertainties on the emission models make not clear to understand what kind and how much information
about the initial emission parameters we can extract from the data. This situation is worsen by priors usually taken by analysts in order to simplify the problem, which hinder a direct comparison among results and could not be reflected in te real explosion.

Searching for Neutrinoless Double Beta Decay: New Results from GERDA Phase II

The GERDA experiment searches for neutrinoless double beta (0νββ) decay of 76Ge using high purity germanium (HPGe) detectors operated in liquid argon (LAr). GERDA relies on improved active background reduction techniques such as pulse shape discrimination (PSD). Phase II of the experiment includes a major upgrade: for further background rejection, the LAr cryostat is instrumented to detect argon scintillation light (LAr veto).

Physics Capabilities of the magnetised Iron Calorimeter detector at the India-based Neutrino Observatory

The proposed 50 kTon magnetised Iron Calorimeter (ICAL) detector at the India-based Neutrino Observatory (INO) aims to detect atmospheric neutrinos and study the effect of Earth matter on their propagation and determine neutrino mass hierarchy. In addition to performing standard oscillation studies, ICAL can probe exotic phenomena like neutrino decay. A study of the sensitivity of the 50 kTon to the invisible decay
of the mass eigenstate ν3 is studied. A full three-generation analysis including earth matter
