Properties of Z{sup 0} {yields} b{bar b}g events

PDF Version Also Available for Download.

Description

We present studies of e{sup +}e{sup -} {yields} b{bar b}g 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: {alpha}{sub s}{sup uds} / {alpha}{sub s}{sup all} = 0.994 {+-} 0.018(stat) {+-} 0.025(syst), {alpha}{sub s}{sup c}/{alpha}{sub s}{sup all} = 1.021 {+-} 0.070 {+-} 0.081, and {alpha}{sub s}{sup b}/{alpha}{sub s}{sup all} = 1.007 {+-} 0.031 {+-} 0.032 (PRELIMINARY).

We also investigated the structure of b{bar b}g events via the energy and polar-angle distributions of the gluon, and the forward-backward production asymmetry of the b-quark.
