Query: Cosmic-Ray Antiprotons from Neutralino Annihilation into Gluons   We estimate the flux of cosmic-ray antiprotons expected from the annihilation
of neutralinos in the galactic halo. The antiproton signal may offer an
important alternative detection scheme in the case that neutralino annihilation
proceeds mainly to the two-gluon final state.
