Dr. Young-Kee Kim has made significant contributions to the understanding of fundamental particles and their interactions while playing a central role in the CDF Collaboration at Fermi National Accelerator Laboratory in the United States. The CDF experiment utilizes a Tevatron facility, a proton-antiproton colliding accelerator with center-of-mass energy of two trillion electron volts. The CDF detector enables investigation of high energy physics phenomena by studying decay processes of particles produced in proton-antiproton collisions. Dr. Kim has made crucial contributions to the design, construction, operation and data analysis of the CDF detector. The Collaboration includes more than 850 scientists worldwide and Dr. Kim is a co-spokesperson of the CDF experiment group. To date, it has been highly unusual for a women to represent a large international research community and Dr. Kim`s position as co-spokesperson attests to the international recognition of her outstanding capabilities.
Dr. Kim has developed an analysis tool for distinguishing gluon and quark jets. She also has made important contributions to the discovery of top quarks and subsequent measurement of their masses. In particular, she has played a crucial role in estimating the mass of the Higgs particle through precision measurement of the top quark mass and weakly interacting W boson mass. In the standard theoretical model, the Higgs particle is widely believed to provide the key to the question of the origin of mass, but is has not yet been discovered. Dr. Kim, while leading the CDF Collaboration at Fermi National Accelerator Laboratory, is currently pouring her efforts into research in the area of Higgs particles. The international community has great expectations that Dr. Kim will continue to play a leading role in making new contributions to the field of physics.
