ATLAS (A Toroidal LHC Apparatus) is the larger of two general purpose detectors located at CERN in Geneva, Switzerland. This experiment is one of the largest collaborations in particle physics consisting of 38 countries, 174 universities and labs, 3000 scientist, and approximately 1000 students. The ATLAS detector is used to collect data from the proton-proton collisions of the LHC using high-resolution calorimeters and large superconductors. LaTech is particularly interested in data captured at ATLAS so we may:

  • search for charged Higgs
  • analyze final state Tau lepton events
  • refine how data is collected and jets are produced
  • study Quantum chromodynamics
  • measure the strong coupling constant
  • study Top Quark physics

ATLAS has a recorded luminosity of 17.9 inverse femtobarns of data as of November 2012. A particle closely matching the Higgs Boson has been detected at ATLAS and the other general purpose experiment CMS. The Chi B (3P) particle was also discovered by ATLAS and was the first particle discovered at the LHC. The particle physics research team at Louisiana Tech University has made determinations of the strong coupling constant, which are the most precise such results from a hadron collider and which have the highest reach in momentum transfer. The university plays an important role in the development and maintenance of the ATLAS trigger.
