Masses, Lifetimes and Production Rates of Xi- and anti-Xi+ at LEP 1
arXiv:hep-ex/0606030 · doi:10.1016/j.physletb.2006.06.029
Abstract
Measurements of the Xi- and anti-Xi+ masses, mass differences, lifetimes and lifetime differences are presented. The anti-Xi+ sample used is much larger than those used previously for such measurements. In addition, the Xi production rates in Z -> b anti-b and Z -> q anti-q events are compared and the position xi* of the maximum of the xi distribution in Z -> q anti-q events is measured.
