Stephen Godfrey received his B.A.Sc. from the University of Toronto in 1976, his M.Sc. from the Weizmann Institute in 1978, and his Ph.D. from the University of Toronto in 1983. He was a postdoctoral fellow at TRIUMF in Vancouver and at Brookhaven National Laboratory before becoming an Assistant Professor at the University of Guelph in 1987. He moved to Carleton University in Ottawa, Canada, in 1990 where he is currently a Professor of Physics. His research is in particle physics phenomenology, ranging from hadron spectroscopy to physics beyond the standard model at the LHC.
The BABAR collaboration at SLAC has observed the radiative decay of an excited state of bottomonium (the bound state of a bottom quark and its antiparticle) to its ground state . Observing this long-sought ground state should enable better tests of quantum chromodynamic calculations of quark interactions and the computational approach called lattice quantum chromodynamics.
