BIDW03 - The Many Faces of Boundaries, Impurities, and Defects

In AdS/CFT the mass of a particle is related to the scaling dimension of the dual operator. I explain how the generalisation to p-branes, which are dual to p-dimensional defects, leads to two independent definitions of invariant brane tension.  I will then prove that superconformal invariance equates them, and discuss implications for the old problem of radiation-reaction for an accelerated charge.
