Abstract

Inclusive b-quark production in two-photon collisions has been measured at LEP using an integrated luminosity of 698 pb(-1) collected by the ALEPH detector with root s between 130 and 209 GeV. The b quarks were identified using lifetime information. The cross section is found to be sigma(e(+)e -> e(+)e(-) bb(-)X) = (5.4 +/- 0.8(stat) +/- 0.8(syst)) pb, which is consistent with Next-to-Leading Order QCD.
