The Experimental Particle physics group conducts research with the D0 experiment at Fermilab, the CMS experiment at the CERN LHC and the CLEO experiment at Cornell. The group also works on linear collider detector development and the CALICE experiment, xs and astroparticle physics experiments RICE, AURA, and ANITA at the South Pole.


CMS The Compact Muon Solenoid (CMS) detector operates at CERN in Geneva, Switzerland. CMS is a large multipurpose experiment that looks at the proton-proton collisions from the Large Hadron Collider with a center of mass energy of from 7-14 TeV. At this energy frontier we search for the Higgs Boson(s), Supersymmetry, and extra dimensions. Also, this project provides the ability to make precision studies of different particles, their processes and interactions. Analysis topics explored by our group include searches for the Higgs Boson decaying to b quarks, b-quark decays, and studies of the single top cross sections. We also operate the silicon tracking detector which we helped to build. We are working with two institutes in Switzerland - PSI and ETH, as well as Kansas State Univ., Univ. of Illinois-Chicago, Univ. of Nebraska and Univ. of Puerto Rico performing pixel R&D for a tracker upgrade for the high luminosity running called the SLHC.

D0We are members of the D0 collaboration working at Fermi National Accelerator Laboratory (Fermilab). The D0 detector studies proton-antiproton collisions at a center-of-mass energy of 2 TeV. We helped with the construction of the silicon detector, to produce enhanced reconstruction of jets associated with the bottom quark. The group also has reponsibilities for the fiber-tracker based track trigger and is engaged in understanding tracking and triggering in D0. Some of our analysis projects include: the discovery of single-top quark production and Bs-oscillations, searches for the Higgs particle, and Electroweak cross section measurements. Faculty on this experiment include Baringer, Bean, and Wilson.

CLEOOur group also analyzes data obtained at the Cornell Electron Storage Ring (CESR) within the CLEO collaboration. The electron-positron collisions at 4 GeV permit the study of weak decay of the charmed and bottom quark, and a search for new forms of matter and novel Upsilon(1s) decays. Prof. Besson leads this effort.

Linear Collider

ILCProf. Wilson works on the design of particle-flow calorimetry for experiments at future electron-positron colliders such as the International Linear Collider. Examples of such high granularity calorimeters are those proposed by the ILD and SiD detector design concepts. We test the calorimetry design concepts with the CALICE test-beam experiment using suitable test-beams around the world.
