Abstract

A measurement of the fraction of hadronic Z decays in which a gluon splits into a bb̄ pair, g_bb̄, is presented using data collected by ALEPH from 1992 to 1995 at the Z resonance. The selection is based on four-jet events. Events are selected by means of topological cuts and a lifetime tag. The result is g_bb̄ = (2.77 + 0.42(stat) + 0.57(syst)) × 10^-3.

N2 - A measurement of the fraction of hadronic Z decays in which a gluon splits into a bb̄ pair, gbb̄, is presented using data collected by ALEPH from 1992 to 1995 at the Z resonance. The selection is based on four-jet events. Events are selected by means of topological cuts and a lifetime tag. The result is gbb̄ = (2.77 + 0.42(stat) + 0.57(syst)) × 10-3.
