Experiments

ATLAS investigates a broad range of physics, including the search for the Higgs boson, extra dimensions, and new particles that could make up dark matter.

It will be an advanced facility for ground based very- high-energy gamma ray astronomy, based on the observation of Cerenkov radiation.

The main goal of the project is to survey 5000 sq. deg. of the southern galactic sky, measuring positions on the sky, shapes and redshifts of about 300 million galaxies and 15000 galaxy clusters.

Euclid is a mission for the European Space Agency (ESA) Cosmic Vision (CV) 2015-25 programme to probe the expansion history of the Universe by carrying out a wide survey of galaxies in 15,000 sq. deg. of the sky. It will be launched in the first quarter of 2020 and the mission will last 6 years.

It is a new generation two-telescope system located at the Roque de los Muchachos Observatory at the La Palma Canary Island.

Solid state pixel detector are used in many detectors in the field of High Energy Physics and the aim of our research line is mold this existing technology into a useful form to service the interest of the public.

The contributions of the IFAE group to the T2K experiment focus on the near detector, specifically in the construction of the time projection chamber and the refurbishing of the old magnet.

PAU is a project with the objective of constructing a large CCD camera for the WHT in La Palma, equipped with many narrow band filters as to be able to provide accurate photometric redshifts for a high density galaxy sample. In a second phase the PAUCam Team will conduct a large survey with this instrument/telescope to study the accelerated expansion of the universe.

Theory

Standard Model

The Standard Model of particle interactions is one of the major achievements of fundamental science. Within this framework a wide range of phenomena can be described to an impressive degree of accuracy. As a matter of fact, few are the branches of Physics where the predictive power of a theory has been tested to such a level of precision. Nevertheless, a number of theoretical and experimental reasons lead physicists to believe that this theory cannot be the ultimate answer in particle physics. Examples in this respect are the lack of neutrino masses and the absence of gravity in the Standard Model. An important route to unveil physics beyond the Standard Model are precision tests of its internal consistency. These, however, require knowledge of the fundamental parameters of the Standard Model as accurately as possible, being one of our research lines.

 

A certain obstacle towards this feat is the fact that the strong interaction sector does not allow for a perturbative treatment, because the fundamental quark and gluon degrees of freedom are confined into the physical observable hadrons. Part of the IFAE Theory Group is concerned with approaches to the theory of strong interactions (QuantumChromoDynamics) in the region of low-energies where the hadronic degrees of freedom prevail. The pursued lines of research include Chiral Perturbation Theory, the expansion for a large number of colour degrees of freedom, QCD sum rules, non-relativistic QCD as well as models of QCD which can be solved analytically. Furthermore, aspects of Flavour Physics and CP violation, such as rare B decays, are currently being investigated by IFAE members. All together these studies allow for a better control of the influence of the Standard Model dynamics in processes investigated for example at the Large Hadron Collider at CERN.
