Tuesday 5th December: STP Seminar – “An M5-Brane Model”

Title: An M5-Brane Model

Speaker: Christian Sämann (Heriot-Watt University)

Abstract: We show how to write an action for a classical six-dimensional superconfomal field theory containing a non-abelian tensor multiplet. All of the ingredients of this action have been available in the literature. We bring these pieces together by choosing the String Lie 2-algebra as a gauge structure which we motivate in some detail. The kinematical data contain a connection on a categorified principal bundle, which is the appropriate mathematical description of the parallel transport of self-dual strings. Our action can be written down for each of the simply laced Dynkin diagrams, and each case reduces to a four-dimensional supersymmetric Yang–Mills theory with corresponding gauge Lie algebra. Our action also reduces nicely to an M2-brane model which is a deformation of the ABJM model.
