Abstract

Inclusive heavy flavour production in gamma gamma collisions has been studied at the LEP collider by ALEPH, L3, and OPAL. Preliminary results on charm and beauty production at roots = 189 GeV are presented. Hadronic final states containing charm particles were identified either by detecting electrons or muons from their semi-leptonic decays or by reconstruction of chargedD* meson decays. The b (b) over bar cross section, the charm structure function F-2,c(gamma) and the high energy behaviour of sigma(gamma gamma --> c(c) over bar) cross section as function of gamma gamma centre-of-mass energy are measured for the first time in two-photon collisions.
