High Energy Physics

Research is conducted on the fundamental structure of matter at the level of elementary particles and their interactions as a central theme, with implications for the understanding of the atomic nuclei and cosmology in the study of the origin and evolution of the universe. The investigation relates to the origin of mass, the asymmetry between matter and antimatter in the universe, the composition of dark matter and the source of the accelerated expansion of the universe: dark energy. The research is experimental, theoretical and phenomenological but it is also applied: High energy particle detectors are used for the production of biomedical images.

Since 1988, the group works with the largest particle accelerators, the Tevatron of Fermilab (Batavia, Illinois, USA) and since 2006 also with the Large Hadron Collider (LHC) from CERN Laboratory (Geneva, Switzerland). At Fermilab, the group is an active member of the international collaboration D-Zero, with which it participated in the 1995 discovery of the quark top, and is now studying diffractive physics processes, about the possible existence of the pomeron particle. In the CERN Laboratory, as a member of the Compact Muon Solenoid Experiment (CMS), the group investigates the search for supersymmetric particles, including neutraline candidates for constituents of dark matter in the Universe. For the analysis of data from the experiments, we use the largest computer network in the world, the GRID with GRID-Uniandes infrastructure, started at the Physics Department. In the High Energy Laboratory at Universidad de Los Andes in Bogota, we work with X-rays and high resolution pixel silicon detectors for the production of biomedical imaging, radiographies and high resolution scans to the scale of micrometers. Since 2008 the group is a member of the Collaboration Medipix3 of the CERN Laboratory, which develops the most advanced semiconductor pixel detectors.
