Description
Everything in our universe is made of matter and not antimatter, and we do not understand why. An exciting possibility is that this asymmetry between baryons and antibaryons was created during the electroweak phase transition, in a process called electroweak baryogenesis. The scenario requires new physics at the electroweak scale, which can be tested by experiments. Much progress has been made in recent years, both on the theoretical and experimental side, with the result that the vanilla implementation of electroweak baryogenesis is now in trouble. I willl give a status update of electroweak baryogenesis, and discuss some of the ways forward.
