  The Standard Model of Particle Physics cannot explain the observed baryon
asymmetry of the Universe. This observation is a clear sign of new physics
beyond the Standard Model. There have been many recent theoretical developments
to address this question. Critically, many new physics models that generate the
baryon asymmetry have a wide range of repercussions for many areas of
theoretical and experimental particle physics. This white paper provides an
overview of such recent theoretical developments with an emphasis on
experimental testability.
