Abstract

We review briefly the sphaleron and list some of its properties. We summarize some of the results in models which have an extended scalar sector. We also present our work on models dealing with physics beyond the standard model. We focus on the energy of the sphaleron which is important in determining the rate of baryon number violation at the electroweak scale.
