Description du projet
Dévoiler comment des symétries cachées façonnent l’univers
Les symétries qui sous-tendent notre description de la nature pourraient répondre à certaines des plus grandioses et des plus inspirantes questions que nous nous posons sur l’univers. Le projet HIDDeN, financé par l’UE, mènera des recherches sur les symétries cachées et sur la manière dont elles affectent les neutrinos, la matière noire et d’autres particules insaisissables. Plus précisément, il explorera la rupture ou l’absence de symétrie CP chez les leptons et dans les interactions fortes, les symétries dans la masse et les schémas de mélange des particules connues et les symétries responsables de la stabilité de la matière noire et de ses interactions. La mission du projet est de former la nouvelle génération de chercheurs pour aborder les questions fondamentales de la physique des particules et de la cosmologie par le biais d’un ambitieux programme de recherche et de formation pluridisciplinaire.
Objectif
Despite huge progress in particle physics and cosmology, most of the Universe’s building blocks and how they function remain hidden to us: Neutrinos are the most abundant known fermion but the reasons why they have mass and mix are unexplained; we have evidence of Dark Matter but we do not even know which particle makes it up; particles and antiparticles show to behave differently (the so-called CP-violation) without a compelling reason; we see that in the Universe there is mostly matter and very little antimatter, but we do not know why this is the case. Symmetries and their breaking will be the guiding principle to address those questions. HIDDeN will focus on revealing the (a)symmetries we have yet to discover, hence hidden (a)symmetries, and the particles on which they act, in particular the invisible sector, made of neutrinos, dark matter and other elusive particles. We will explore simultaneously the puzzles related to the CP symmetry in the lepton sector as well as in strong-interactions (the latter leading to axions and axion-like particles), (a)symmetries in the mass and mixing patterns of known particles, (a)symmetries responsible for the dark matter stability and its interactions. And we will address a key question: are all these sectors part of a new HIDDeN sector whose discovery will lead us to the New Standard Model?
The mission of the HIDDeN ITN is to train the new generation of researchers to address these most fundamental questions via an ambitious multidisciplinary research and training program. We focus on phenomenological studies and include crucial links to experiments and industrial partners. We bundle world leadership in phenomenology research and our network includes representatives of key-experiments and laboratories on the field, such as CERN, Fermilab, SuperKamiokande, ADMX. An innovative aspect is the integration of a dedicated training program in outreach and journalism focussed on the Invisible Universe.
