Study of Double-Scattering Effects inp¯dAnnihilation Processes

Abstract

The characteristics of the surviving nucleon in $\overline{p}d$ annihilation are analyzed in terms of a double-scattering model with only two free parameters. Evidence is presented that the surviving nucleons not only may be very different dynamically from the true-spectator nucleon in the annihilation process, but also may have a different identity through charge exchange in the double-scattering process.
