Hunting Invisibles: Dark sectors, Dark matter and Neutrinos

Project description

Revealing how hidden symmetries shape the universe

The symmetries underpinning our description of nature could answer some of the most inspiring and grand questions we have about the universe. The EU-funded HIDDeN project will conduct research on hidden symmetries and how they affect neutrinos, dark matter and other elusive particles. Specifically, it will explore CP symmetry breaking, or the lack of it, in leptons and strong interactions, symmetries in the mass and mixing patterns of known particles and symmetries responsible for dark matter stability and its interactions. The project's mission is to train the new generation of researchers to address fundamental questions in particle physics and cosmology via an ambitious multidisciplinary research and training programme.

Objective

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.
