Bethe Forum on String Cosmology

15.06.2015 – 19.06.2015
String Cosmology Poster
The Bethe Forum on String Cosmology is a one week program which brings together experts in cosmology and string theory. Among other topics, the advances and challenges in embedding inflation in string theory are discussed. The workshop takes place from June 15th to June 19th. More information about the program and the registration can be found here.

Bethe Colloquium by Prof. Henry S.-H. Tye

June 2015
Henry S.-H. Tye

June's Bethe Colloquium will take place on June 18th (3:15 pm) in Hörsaal I:

  • Henry S.-H. Tye (Cornell University)
  • Sphaleron and Baryon Number Violating Processes
  • Hörsaal I, Physikalisches Institut

Abstract: It is known that baryon number violating processes are allowed in elecrotroweak theory, but they are believed to be exponentially suppressed. I like to argue otherwise. The reasoning is based on the periodicity property of the sphaleron potential in the electroweak theory, where we write down the one-dimensional time-independent Schr\"{o}dinger equation with the Chern-Simons number as the coordinate. The baryon-lepton number violating processes may even take place at LHC soon.
