Neutral Associated Production by 8-, 10.7-, and 15.7−GeVc π− Incident on Protons

We present differential and total cross sections for two reactions: ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{K}^{0}\ensuremath{\Lambda}$ and ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{K}^{0}{\ensuremath{\Sigma}}^{0}$. The incident pion momenta were 8, 10.7, and 15.7 $\frac{\mathrm{GeV}}{c}$. The results are based on an analysis of approximately 22 600 events of the two reactions where the ${\ensuremath{\pi}}^{+}$ and ${\ensuremath{\pi}}^{\ensuremath{-}}$ from the decay of the ${K}_{S}^{0}$ were detected in the forward leg of the Double Vee Magnetic Spectrometer. The separation of $\ensuremath{\Lambda}$ recoils from ${\ensuremath{\Sigma}}^{0}$ recoils was accomplished by the missing-mass technique.
