The Standard Model of Particle Physics via Non-Commutative Geometry – Latham Boyle

I will introduce Connes’ notion of non-commutative geometry, and explain how it offers a novel geometric perspective on certain otherwise unexplained features of the standard model of particle physics, and a more restrictive framework than effective field theory for exploring physics beyond the standard model. I will also explain the main ideas behind a new reformulation of NCG which has certain key mathematical and physical advantages over Connes’ traditional “spectral triple” formulation. In this reformulation, the traditional NCG axioms are considerably simplified and unified; a number of problematic issues in the traditional NCG construction of the standard model are fixed; and a certain extension of the standard model of particle physics (with two new particles) is predicted.
