Rapidity and charge correlations of centrally produced charged particles in events with a high-momentum. pi. /sup 0/ near 11/sup 0/

Rapidity and charge distributions have been measured for central charged tracks in events at center-of-mass energy 63 GeV, triggered on a ..pi../sup 0/ near 11/sup 0/ with transverse momentum greater than 2.25 GeV/c. The observed distributions are consistent with parton-parton scattering models with a spin-one gluon, and inconsistent with the exchange of a spin-zero gluon.
