Abstract:	The inclusive production of $Ξ^{+}$ and Ξ^? hyperons is investigated in K⁺ p interactions at 32 GeV/c. The production cross sections, 36.4±9 μb for the $Ξ^{+}$ and 6.5±3 μb for the Ξ^?, are rising strongly with energy similarly to $Λ$ and Λ production in K⁺ p interactions. The $Ξ^{+}$ are produced preferentially in the forward direction in the c.m.s., while the Ξ^? are produced dominantly backwards. The average transverse momenta $〈p_{T} 〉_{Ξ^{+}} =0.73±0.09 GeV /c$ and 〈p_T〉_Ξ^?=0.58±0.09 GeV/c.
