"It is a great honour to receive the 2022 CAP-CRM Prize in Theoretical and Mathematical Physics. But I must also acknowledge the enormous contributions of my many collaborators, postdocs and students over the years: you also deserve a share of this award. Thank you." winner citation

The Canadian Association of Physicists (CAP) and the Centre de recherches mathématiques (CRM) are pleased to announce that the 2022 CAP-CRM Prize in Theoretical and Mathematical Physics is awarded to David London, Université de Montréal, in recognition of his outstanding contributions to the theory of elementary particles, including trailblazing contributions to the analysis of B meson decays and CP violation in the Standard Model of particle physics. announcement

The Standard Model (SM) of particle physics is a first step towards the ultimate goal of describing all the fundamental particles of nature, as well as the forces with which they interact, within in a single mathematical framework. The SM has yielded hundreds of predictions, almost all of which have been verified. There is little doubt that the SM is correct. However, it is not complete. For example, dark matter is the most prevalent form of matter in the universe, but the SM tells us nothing about it. For this and several other reasons, 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.

David London is a particle theorist with an international reputation. Throughout his career, he has examined many different possibilities for the new physics. He is best known for his work in B physics. The B-factories BaBar (SLAC, California) and Belle (Japan) were built in the 1990s and took data throughout the 2000s. Their goal was to study the properties of B mesons, looking for discrepancies with the predictions of the SM. 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.

Dr. London has also studied a wide variety of other new-physics possibilities. On the one hand, he has used experimental results to put constraints on different types of new physics. On the other hand, he has developed new-physics models and detailed the signals which can be measured at future colliders to identify them. It is for this pursuit of physics beyond the SM that David is awarded the CAP-CRM Prize in Theoretical and Mathematical Physics. nominator citation
