The University of Iowa CMS (Compact Muon Solenoid) research group in the Department of Physics and Astronomy recently originated and completed an analysis which led to the discovery of a new and unexpected particle in proton-proton collision data recorded by the CMS detector.

The group has worked on the CMS experiment for 20 years, and led the design and construction of part of the detector at the Large Hadron Collider (LHC), the world's largest atom smasher, located at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland.

The UI CMS group has 25 members, including faculty, research scientists,
postdoctoral scholars, graduate, and undergraduate students. Members of the group who worked on this analysis include: professor Yasar Onel, associate professor Jane Nachtman, research scientist Kai Yi, research-affiliated scholar Elif Asli Albayrak, and graduate student Maksat Haytmyradov.
