High-energy physics encompasses the study of the fundamental particles and interactions between particles that make up our Universe. This includes dark matter and dark energy. The group at Texas A&M, housed within the Mitchell Institute for Fundamental Physics and Astronomy, consists of theory and experimental groups working on the cutting edge of these questions. Scientists work at the Large Hadron Collider (LHC) as well as on direct and indirect searches for the particles of dark matter with the Super CDMS, LUX and Fermi experiments. This also includes the design and construction of accelerators for use in creating particle collisions. On the other hand, some of our scientists work on the fundamental principles of string theory and gravity, as well as on the interface between cosmology, dark matter, models and phenomenology.
