Abstract
An experimental study of two jet production by interactions of two quasi-real photons is presented. The data for production of jets with high transverse momentum squared, p 2T >10GeV2, are found to be consistent with the fractionally charged quark-parton model. If gauge integer charged quark models are considered, then the gluon mass is less than 5 MeV at the 95% confidence level.
