Properties of Z0 → b bar bg events
- 1. Nagoya Univ. (Japan)
Description
We present studies of e+e- → b bar bg events recorded with SLC Large Detector(SLD) at the SLAC Linear Collider. The SLD precision vertex detector was exploited to select light quarks- (u,d, and s), c-, and b-enriched event samples. A comparison of the strong couplings of light, c, and b quarks was made using jet rates in these samples. We find: αsuds / αsall = 0.994 ± 0.018(stat) ± 0.025(syst), αsc/αsall = 1.021 ± 0.070 ± 0.081, and αsb/αsall = 1.007 ± 0.031 ± 0.032 (PRELIMINARY). We also investigated the structure of b bar bg events via the energy and polar-angle distributions of the gluon, and the forward-backward production asymmetry of the b-quark
