The reaction p-bar p -> K+ K- has been studied for incident antiproton momenta between 1.3 and 1.5 GeV/c. A continuous scan has been made for invariant masses of the p-bar p system between 2220 and 2240 MeV/c2 with a resolution of 0.6 MeV/c2 in the ξ (2230) region. No structure has been observed.

Abstract
The reaction p-bar p -> K+ K- has been studied for incident antiproton momenta between 1.3 and 1.5 GeV/c. A continuous scan has been made for invariant masses of the p-bar p system between 2220 and 2240 MeV/c2 with a resolution of 0.6 MeV/c2 in the ξ (2230) region. No structure has been observed. Upper limits are given.File in questo prodotto:
