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 (s)1/2 between 130 and 209 GeV. The b quarks were identified using lifetime information. The cross section is found to be which is consistent with Next-to-Leading Order QCD.
