Abstract

The reactions e(+)e(-) --> e(+)e(-) LambdaX and e(+)e(-) --> e(+)e(-) LambdaX are studied using data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 209 GeV. Inclusive differential cross sections are measured as a function of the lambda transverse momentum, p(t), and pseudo-rapidity, eta, in the ranges 0.4 GeV < p(t) < 2.5 GeV and \eta\ < 1.2. The data are compared to Monte Carlo predictions. The differential cross section as a function of pt is well described by an exponential of the form A exp(-p(t) /)
