Compact Muon Solenoid Experiment
The Purdue particle physics group was a founding member of the CMS experiment and made important contributions to the construction of the detector and its commissioning. The group played a major role in the construction of the existing CMS forward pixel detector, hadron calorimeter, endcap-muon detector, and the high-level trigger. The group is deeply involved in detector upgrade projects using an in-house facility for micro-electronics assembly and characterization, the Purdue Silicon Detector Lab (PSDL), to design, develop and build silicon detectors. The PSDL is currently used for the construction of the phase-1 upgrade of the CMS Forward Pixel Detector. Purdue is one of the seven US CMS Tier-2 analysis centers, providing resources for data analysis both locally and as part of the Grid.
The physics focus of the high energy physics group is on the precise investigation of the Higgs boson, precision measurements of the Standard Model and searches for physics beyond the Standard Model. Various members of the group have leadership positions in physics analysis as well as in construction and commissioning of the detector operations. The Purdue CMS group significantly contributed to the first W and Z cross section measurement, the measurement of the Upsilon differential cross section and to the first measurement of the J/ψ cross section and the measurement of the differential Drell-Yan cross section.
Currently the main focus of the Purdue high energy physics group is on measurements of the double-differential Drell-Yan cross section, angular distribution of Z decays, properties and production cross sections of Higgs bosons and top quarks as well as their interaction with eachother. With the LHC operating at unprecedented high energies the Purdue group members search for new physics beyond the standard model via displaced dimuon vertices at large distances from the interaction point and via searches for top quark partners.
Please check the Open Positions page for current openings of Ph.D. positions or other positions in the particle physics groups at Purdue.
The Purdue particle physics group has also a prominent high energy nuclear physics group working on all aspects of heavy ion physics, which is an integral part of CMS.
The CMS groups at Purdue work on a variety of projects related to Instrumentation/Software and Physics analysis that are critical to the success of CMS.
