Abstract

The rapidity distribution of fast fragments of scattered partons has been measured in events triggered on a π+ of large transverse momentum, pT > 4 GeV/c. The energy was √s = 63 GeV. The data are compared to model calculations assuming spin-0 or spin-1 for the quantum exchanged in the underlying parton-parton scattering process. While the exchange of a spin-0 gluon is excluded by the data, a spin-1 gluon is found in agreement with the observations.
