Research Interests

The objective of Prof. Ruchti’s research program is the study of the fundamental questions at the high energy frontier (TeV scale), with particular emphasis on experiments performed at hadron colliders. Key areas of interest include testing of the Standard Model of Electroweak Interactions and search for physics beyond the Standard Model, including searches for evidence of Supersymmetry, investigation of electroweak symmetry breaking (the Higg’s sector), and searches for extra dimensions of space-time. The research program is based around the D0 Experiment at the Tevatron Collider at the Fermi National Accelerator Laboratory and experimentation at the CERN Large Hadron Collider (LHC) using the CMS detector.

The quest for the understanding of fundamental particles and forces has led to the development of new detector technologies which are capable of extracting new and rare phenomena from the harsh and complex experimental environment at hadron colliders. His Notre Dame collider physics group has pioneered one of these: scintillating fiber (SciFi) tracking technology, which combines the speed and efficiency of a scintillation detector and the flexibility and robustness of organic-plastic optical fibers. A major application of this technology is the 80k channel Central Fiber Tracker used in the D0 Experiment. Ruchti’s group continues to develop new scintillator and waveshifter materials and optical readout systems for particle detection and hadronic calorimetry for the CMS detector upgrade and for general particle detector applications.

To carry out the complex and long-term particle physics experiments, a strong program of education and outreach called QuarkNet is under way which partners high school teachers and students from around the USA in immersive research experiences with experimental particle physicists working on a dozen experiments. Ruchti is one of the cofounders of QuarkNet, which consists of over 50 Centers in 25 states and Puerto Rico, and which enjoys the annual participation of over 450 high school teachers, 100 high school students, and 150 particle physicist mentors.
