AN IMPROVED MEASUREMENT OF B(0)-(B)BAR(0) MIXING IN Z(0) DECAYS

AN IMPROVED MEASUREMENT OF B(0)-(B)BAR(0) MIXING IN Z(0) DECAYS

A more precise determination of the B0-B0 mixing parameter in Z0 decays based on a fourfold increase in statistics has been made using the 1990 and 1991 L3 data. The analysis of the dilepton events, muons and electrons, gives: χB = 0.121 ± 0.017 (stat) ± 0.006 (sys). Using the value of χd measured a...
