Is there a new symmetry in nature, such as supersymmetry (SUSY), that explains the stability of the electroweak scale? The origin of the electroweak scale along with a better understanding of the flavour and properties of neutrinos are among the most important questions in basic science today. Building on Europe's long tradition in particle physics, the Large Hadron Collider (LHC) experimental programme is designed to elucidate the origin of the electroweak scale and the properties of matter at teraelectronvolt energies. Could the LHC also help us understand neutrinos and flavour? Neutrinos are elementary constituents of nature and fundamental building blocks of the so-called Standard Model that describes matter and its interactions. The discovery of the neutrino mass has been a revolution in particle physics, providing strong evidence of new physics that implies that the Standard Model, which explains the other experimental results, needs to be revised. Of all the elementary particles, neutrinos play a special role. What is the origin of their mass, why is it so small, is the lepton number conserved, and can we understand from first principles the observed mixing pattern of...Is there a new symmetry in nature, such as supersymmetry (SUSY), that explains the stability of the electroweak scale?

The discovery of the neutrino mass has been a revolution in particle physics, providing strong evidence of new physics that implies that the Standard Model, which explains the other experimental results, needs to be revised. Of all the elementary particles, neutrinos play a special role. What is the origin of their mass, why is it so small, is the lepton number conserved, and can we understand from first principles the observed mixing pattern of neutrinos, which is so different from that of quarks? Our research group has proposed theoretical models where the origin of the neutrino mass is intrinsically supersymmetric, relating the decay properties of the lightest supersymmetric particle to neutrino oscillation angles measured in underground experiments and confirmed by detecting neutrinos from accelerators and nuclear reactors. This line opens up the tantalising possibility that the LHC programme could help us shed light on the flavour problem and requires dedicated scrutiny, both theoretically and at the level of numerical simulations, which will be one of the priorities of our group in the coming years. In the last two decades it has become clear that particle and astroparticle physics offer complementary ways of understanding the Universe and provide answers to the big questions of basic science. Europe is strongly involved in this issue, recognised by the Aspera roadmap to which Spain contributes decisively. We will also investigate how LHC data can help solve astrophysical mysteries such as the nature of dark matter and its properties. The synergies between high-energy physics and astrophysics or cosmology lie at the heart of a new discipline forged in recent decades and now known as astroparticle physics. Our lines of research for the period 2014-2017 are structured as follows:
Neutrino properties: in the laboratory, astrophysics and cosmology.
Origin of the neutrino mass and the flavour problem.
New physics in the LHC era.
Dark matter in astrophysics, particle physics and cosmology. The proposed research is therefore interdisciplinary, covering all aspects of the search for new physics, from theory to experiments, on all sides. More theoretical ideas on unification, extra dimensions, inflationary cosmology and dark energy are also included.
