CPT Student Seminar: Toy Models for Holographic Baryons

Presented by Matthew Elliot-Ripley, Durham University

20 April 2015 17:15 in OC218

Inspired by the AdS/CFT correspondence and by Skyrme theory (a low-energy effective field theory for baryons), there have been many attempts to use holography as a way of studying strongly-coupled QCD. The pre-eminent example of this is the Sakai-Sugimoto model, in which bulk Yang-Mills instantons in five spacetime dimensions are dual to boundary Skyrmions (which in turn represent baryons). In this talk I will discuss some lower-dimensional analogues of this model, in which modifications to an O(2) sigma model in three spacetime dimensions take the place of the 5-d Yang-Mills instanton of the Sakai-Sugimoto model.

A gathering of mathematicians from the CPT group with physicists from IPPP, we meet to discuss our work in a relaxed and friendly environment.
