Fermilab collides protons and antiprotons at the current energy frontier, and our group has a rich history of measuring the lifetimes of B hadrons with the D0 Experiment. Recently, we have been involved in the first observation of B_s oscillations, the Ξ_b baryon discovery, and searches for CP violation in the B_c system. We also have newer interests in high-pT processes, namely the production of W bosons, vector boson fusion, and dijet angular distributions. These measurements provide stringent tests of the theory of QED and QCD, are important for tuning MC models we rely on, and serve as a test bed for the experimental techniques which will be used in the next generation of collider experiments at the Large Hadron Collider (LHC). D0 is a collaboration of about 600 physicists, engineers and technicians from 18 different countries. To learn more, visit our IU D0 page.

Our group's other main activity is preparing for the turn on of the LHC, which is anticipated for the fall of 2009. The energy reach of the LHC will supercede the Tevatron by nearly an order of magnitude. The scientific community anticipates that the discoveries made at the LHC will either complete the Standard Model with the discovery of the Higgs Boson, or change our paradigm drastically through the discovery of new particles, interactions or extra dimensions.. We have been working for several years on the building and commissioning of the Transition Radiation Tracker (TRT), which will play a vital role in all measurements made at the ATLAS experiment. Because of the TRT's special ability to measure heavily ionizing particles, our group has a keen interest in searches for charged massive stable new particles. We are also very active in searches for new resonances in highly boosted top quark events and searches for the Higgs Boson. ATLAS is a collaboration of around 2500 physicists, engineers and technicians from 38 different countries. To learn more, visit our IU ATLAS page.
