Biography

Benjamin Grinstein is a Distinguished Professor in the Department of Physics at the University of California, San Diego. He earned his Ph.D. from Harvard in 1984. His primary research interest focuses on the study of weak interactions, particularly the decays of strange, charm, and bottom quarks. He investigates the weak force, which is responsible for these decays, and its relation to radioactive decays of elements involving down quarks. Grinstein's work contributes to understanding the four of seventeen fundamental parameters of the standard model of strong electroweak interactions, commonly referred to as 'Mixing Angles', which determine the decay rates of quarks. His research is significant in determining these fundamental parameters and enhances the comprehension of bottom quark decays.
