Abstract

We have investigated the inclusive production of $γ$ , $K_{S}^{0}$ , $Λ^{0}$ , and ${\bar{Λ}}^{0}$ in 100-GeV/c $\bar{p} p$ interactions in the 30-in. hydrogen bubble chamber at Fermilab. We present various inclusive distributions and compare them with corresponding distributions in 100-GeV/c $pp$ interactions and lower-energy $\bar{p} p$ interactions. We find some evidence for $Σ (1385)$ production but none for $K^{*} (890)$ production. We find evidence for a nonzero $Λ^{0}$ polarization of -0.45 ± 0.21.
