摘要：

Baryon number violation in the electroweak standard model proceeds over and around the sphaleron barrier connecting vacua of different Chern-Simons number. The sphaleron is a static, but metastable state which has two basic modes of decay, one producing predominantly leptons and baryons, the other, antileptons and antibaryons. This paper makes a careful examination of this phenomenon.
