From an analysis of inclusive leptons in data collected by the ALEPH detector at LEP, we measure the fractions of bView the MathML source and cView the MathML source events in hadronic Z decays. The bView the MathML source fraction times semileptonic branching ratio is measured to be View the MathML source. Assuming a b semileptonic branching ratio of 0.102 ± 0.010 gives View the MathML source, in good agreement with the standard model prediction of 0.217. The cView the MathML source fraction times semileptonic branching ratio is measured to be View the MathML source. Assuming a c semileptonic branching ratio of 0.090 ± 0.013 gives View the MathML source, in agreement with the standard model prediction of 0.171.

Abstract

From an analysis of inclusive leptons in data collected by the ALEPH detector at LEP, we measure the fractions of bView the MathML source and cView the MathML source events in hadronic Z decays. The bView the MathML source fraction times semileptonic branching ratio is measured to be View the MathML source. Assuming a b semileptonic branching ratio of 0.102 ± 0.010 gives View the MathML source, in good agreement with the standard model prediction of 0.217. The cView the MathML source fraction times semileptonic branching ratio is measured to be View the MathML source. Assuming a c semileptonic branching ratio of 0.090 ± 0.013 gives View the MathML source, in agreement with the standard model prediction of 0.171.
