The Experimental Particle physics group at KU conducts research with the CMS experiment on the LHC at CERN, including analysis with multiple subjects and testing of detector modules to be installed in the detector. The group also works on Linear Collider detector development.
The Compact Muon Solenoid (CMS) detector operates on the Large Hadron Collider (LHC) at CERN (European Organization for Nuclear Research) in Geneva, Switzerland. The LHC speeds protons around the underground tunnel at near the speed of light and collides them with a center of mass energy ranging from 7 to 14 TeV. At this extremely high energy frontier, particle physicists search for new fundamental particles, supersymmetry and extra dimensions.
The LHC and its accompanying detectors also allow for precision studies of different particles, their processes and their interactions. Analysis topics explored by our group at KU include the search and subsequent study of the Higgs Boson when decaying to bottom quarks, bottom quark decays, studies of singly produced top quarks, as well as searches for a t’ quark.
We also help to operate the silicon tracking detector which we helped build. Currently at KU, we are helping to test modules and the electronics readout chain for a new silicon pixel detector to be installed at CMS around 2017.
Prof. 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.
