The 2014 CAP-TRIUMF Vogt Medal for Contributions to Subatomic Physics

is awarded to

David London

"Canada's activities in the field of subatomic physics are extremely deep and varied. Its world-class researchers are involved in a wide range of subjects, including phenomenology, cosmology and more formal topics on the theory side, and collider physics, B factories and astroparticle physics on the experimental side. It is an enormous honour to be selected from among them and to be awarded the 2014 CAP-TRIUMF Vogt Medal." winner citation

The Canadian Association of Physicists (CAP) and TRIUMF are pleased to announce that the 2014 CAP-TRIUMF Vogt Medal for Contributions to Subatomic Physics is awarded to David London, Universite de Montreal, in recognition of for his seminal contributions to theoretical physics especially in the field B physics. announcement

The Standard Model (SM) of particle physics is the theory that describes all the fundamental particles of nature, as well as most of the forces with which they interact. It has yielded hundreds of predictions, almost all of which have been verified. There is little doubt that the SM is correct. Nevertheless, for a variety of reasons, most particle physicists do not believe it is complete - there must exist new particles and new phenomena not described by the SM. The search for this "new physics" is the driving force behind most research in particle physics today, both theoretical and experimental. David London is a world-reknowned particle theorist. He is best known for his work in B physics. The B-factories BaBar (SLAC, California) and Belle (Japan) were built in the 1990's, and took data for over a decade until 2008 (BaBar) and 2010 (Belle). Their goal was to study the properties of B mesons, in particular to test the SM explanation of CP violation. (CP is the symmetry which relates matter and antimatter.) If this explanation were insufficient, it would be a clear sign of new physics. Dr. London was very active in this endeavour { many of the principal measurements made at the B-factories were done using techniques proposed by him and his collaborators. Although some hints of disagreements with the SM were observed, nothing conclusive has yet been established. Dr. London has also studied a variety of specific possibilities for the new physics. On the one hand, he has used experimental results to put constraints on new-physics models. On the other hand, he has described the new-physics signals which can be seen at future colliders. It is for this pursuit of physics beyond the SM that David is awarded the CAP-TRIUMF Vogt Medal. nominator citation
