# Sphalerons

## Why is it interesting?

Sphalerons are an important part of several proposed solutions of the Baryon asymmetry problem such as Leptogenesis.

## Layman

Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party.

## Student

A sphaleron is a maximum of the energy functional in the direction of changing winding number, and a minimum in the orthogonal direction. Thus it is a saddle point. (page 336 in An introduction to gauge theories and modern particle physics by E. Leader and E. Predazzi.)

## Researcher

The motto in this section is: the higher the level of abstraction, the better.
