Inclusive differential cross sections are measured as a function of the lambda transverse momentum, pt, and pseudo-rapidity, η, in the ranges 0.4 GeV<2.5 GeV and |η|<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 Aexp(−pt/〈pt〉).
