Abstract

Inclusive production of D*(+/-) mesons in two-photon collisions was measured by the L3 experiment at LEP. The data were collected at a centre-of-mass energy root s = 189 GeV with an integrated luminosity of 176.4 pb(-1). Differential cross sections of the process e(+)e- --> e(+)e(-) D* X+/- are determined as functions of the transverse momentum and pseudorapidity of the D*(+/-) mesons in the kinematic region 1 GeV
