Description
The radiation emitted by an accelerated charged particle is one of the most basic observables in gauge theories and is governed by the Bremsstrahlung function. While this quantity can be computed exactly in Maxwell theory, its generalization to non-Abelian gauge theories is far more intricate. In superconformal field theories, however, the enhanced symmetry structure provides powerful tools to make the problem accessible. I will discuss recent developments in deriving exact results for the Bremsstrahlung function at arbitrary coupling using localization in the planar limit of different superconformal gauge theories. I will then focus on the strong-coupling regime of these models and analyze this quantity using analytical methods.
