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 also works on physics and detector studies for experiments at a future electron-positron collider such as the International Linear Collider (ILC). Detector work is on the design of the ILD detector concept with an emphasis on calorimetry and particle-flow based jet energy reconstruction. Physics work is focused on experimental issues which help define the scope of the accelerator and the scientific program. In particular methods for in-situ measurements of absolute center-of-mass energy, beam polarization and jet energy scale leading to measurements of unprecedented precision for the masses of the W, top and Higgs.
