| Abstract: | Baryon pair production in two-photon collisions is studied with the L3 detector at LEP using data collected at e+e- center of mass energies from 91 GeV to 209 GeV with an integrated luminosity of 844 pb-1. The four processes  ,  ,  and  are identified. The cross section for these processes as a function of the γγ center of mass energy is measured for the first time at LEP and results are compared to quark-diquark model predictions. |
