Decay Rate Difference in the Neutral B-System: Delta Gamma Bs and Delta Gamma Bd

Abstract

We review the theoretical status of the predictions for the decay rate differences in the neutral B-system. We find (Delta Gamma/Gamma) Bs = (12 pm 5) 10^(-2) and (Delta Gamma/Gamma) Bd = (3 pm 1.2) 10^(-3).
