ATLAS is a multi-purpose detector at the Large Hadron Collider at the CERN laboratory in Geneva, Switzerland. It is a general-purpose detector, with some of the primary goals being to look for the Higgs boson and study its properties if it is found, to look for supersymmetric particles, and to look for new physics such as extra dimensions and mini black holes. The collaboration consists of over 3000 physicists and engineers from 18 countries.
BaBar is a detector at the SLAC National Accelerator Laboratory in Stanford, CA. It took data from 2000 to 2009, with analysis continuing. The primary physics goal is to study in detail symmetry-breaking properties of the weak interaction. The name BaBar® is used by permission from Laurent. deBrunhoff.
D0 is a detector at the Tevatron Collider at theFermi National Accelerator Laboratory near Batavia, IL. Until recently, the Tevatron Collider provided the highest energy collisions in the world. The research is focused on precise studies of interactions of protons and antiprotons at the highest available energies, with a particular emphasis on searching for the Higgs boson.
DREAM is a group at the CERN laboratory in Geneva, Switzerland, that is developing new techniques for precision measurements in high energy physics.
The Fourth Detector is being developed by a team for possible use at a future International Linear Collider, which is currently being studied.
The experimental neutrino group is doing research on neutrino oscillations using long baseline experiments such as MINOS, NOvA and LBNE. These US-based experiments send beams of neutrinos from Fermilab to be caught by very large particle physics detectors hundreds of miles away. This work allows us to measure crucial properties of neutrino mixing that could open the door to a better understanding our Universe.
Next is a delicate search for neutrino-less double-beta decay in the Canfranc tunnel under the Pyrenees mountains. This experiment is very new and uses 100 kg of enriched Xenon isotope-136 at 15 atmospheres pressure in a large TPC (Time Projection Chamber) with electroluminescent gain. The energy resolution is already tested at better than 0.5% and, combined with the 3-dimensional imaging of a TPC, we expect to be the best in the world.
The theory group works on a variety of problems, including phenomenological research in electroweak interactions within the standard model and beyond, and the study of the phenomenology of neutrino interctions.
