What Do Grassmannians And Particle Colliders Have In Common?
Speaker(s): Freddy Cachazo
Abstract: In the past year, motivated by physics, a rich structure has emerged from studying certain contour integrals in Grassmannians. Physical considerations single out a natural meromorphic form in G(k,n) with a cyclic structure. The residues obtained from these contour integrals have been shown to be inv... read more

The S-matrix reloaded
Speaker(s): Freddy Cachazo
Abstract: In the 60’s, the analytic S-matrix program was developed in an attempt to describe the strong interactions – at the time, this was a theory of massive particles like pions. The S-matrix is an object that encodes the information of the probability of producing a certain set of final particles fro... read more

From Symmetries to String Theory
Speaker(s): Freddy Cachazo
Abstract: Symmetry principles in physics are a very powerful guiding principle. Sometimes they are so powerful that they can determine a theory completely. This talk will be a tour from the Standard Model of particle physics to string theory compactifications using mostly symmetry arguments.
