ResumoWe present measurements of the production symmetric high-mass hadron and pion pairs by protons of 200, 300, and 400 GeV, incident on a beryllium target. The two-particle invariant cross section for pion production can be described by the function $\frac{{E}_{1}{E}_{2}{d}^{6}\ensuremath{\sigma}}{d{{p}_{1}}^{3}d{{p}_{2}}^{3}}=(1.7\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}28}){{p}_{t}}^{\ensuremath{-}8.4}{(1\ensuremath{-}{x}_{t})}^{14}$ ${\mathrm{cm}}^{2}$/Ge${\mathrm{V}}^{4}$ (where ${p}_{t}$ is the mean ${p}_{t}$ of the two hadrons). Functions of the same form have been used in describing single-pion inclusive production. Equality of the exponents of ${p}_{t}$ in the two processes is observed, confirming the role of smearing contributions to single-hadron cross sections.
