Neutral-particle production in π-p interactions at 147 GeV/c and comparison to charged-particle production

The production of ${K}_{S}$, $\ensuremath{\Lambda}$, $\overline{\ensuremath{\Lambda}}$, and $\ensuremath{\gamma}$ in ${\ensuremath{\pi}}^{\ensuremath{-}}p$ collisions at 147 GeV/c is analyzed. Cross sections, rapidity, Feynman-$x$, and ${{p}_{T}}^{2}$ distributions are presented and compared to charged-particle production. The energy dependence of multiplicities in ${\ensuremath{\pi}}^{\ensuremath{-}}p$ and $\mathrm{pp}$ collisions is shown. A new scaling form for the correlation of neutral- and charged-particle multiplicities is presented for compilations of $\ensuremath{\pi}p$ and $\mathrm{pp}$ data.
