Search forΞ*resonances in 2.87-GeV /cK−ninteractions

Abstract

We report on a search for ${\Xi }^{*}$ production in the mass range 1.5-2.0 GeV / ${\mathit{c}}^2$ in $K^{-}n$ interactions at 2.87 GeV / c. Upper limits on ${\Xi }^{*}$ production cross sections, as well as reaction cross sections for those final states in which ${\Xi }^{*}\text{'}s$ may be observed, are presented. In particular, an upper limit of 5.4 μb is placed on production of an isospin-$-\frac{3}{2}$ ${\Xi }^{*--}$.
