Upper Limit on Beauty Lifetime and Lower Limit on Weak Mixing Angles

摘要

Muons from a multihadron sample are used to determine an upper limit tau < 1.4 x 10 exp -12 sec (95% CL) on the lifetime of beauty particles. The data are obtained with the JADE detector at PETRA. The result is interpreted within the standard model. (ERA citation 08:008530)
