Stephen Reucroft

physicist and syndicated columnist

Stephen Reucroft is Emeritus Matthews Distinguished University Professor of Physics at Northeastern University. He received his PhD in particle physics from Liverpool University. The first 20 years of Reucroft's career were devoted to precision determinations of challenging quantities using specially designed, high-resolution bubble chambers. These include resonance properties, hyperon magnetic moments, and charm particle production and decay characteristics. The latter is particularly noteworthy since the CERN bubble chamber LEBC was specially designed to investigate charm particle properties, and Reucroft was one of the inventors and prime motivators of the LEBC technique. He was leader of both CERN and Fermilab experiments. Since leaving CERN and joining Northeastern University, he has devoted his efforts to experiments at the highest energy colliders. He spent significant time developing the scintillating fiber technique and successfully tested it with the tracking system in L3. He is also part of research teams that have studied QCD (quantum chromodynamics) and QED (Quantum electrodynamics), discovered and studied the t-quark, and confirmed that there are three and only three generations of light neutrinos. Reucroft is presently an active participant in the CMS experiment at CERN. He has a wide range of experience in international collaboration and has been a spokesman for major international experiments. He is coauthor (with John Swain) of the syndicated column "Science Briefs," published in *The Boston Globe*.
