John Cumalat

Professor. Ph.D., University of California, Santa Barbara, 1977. Robert R. Wilson Fellow; Department of Energy Outstanding Junior Investigator Award; Fellow, American Physical Society.

Professor Cumalat's research area is experimental elementary particle physics. His research involves the study of the strong interaction production mechanisms and the subsequent weak decay of charm and beauty states. Of particular interest is the quark mixing between the meson-antimeson states and in establishing the spectra of charm baryon excited states. These states are produced in high energy interactions of energy tagged photons on a fixed target. The research is performed at Fermi National Accelerator Laboratory in Illinois in a group consisting of roughly 120 physicists from Italy and the United States. During the past several years Professor Cumalat has served as the spokesman for this project.

His research also involves the development of new detectors and techniques to be used for elementary particle detection.
