Measurement Of The (P)Over-Bar-P -> Ksks Eta Cross Section At Beam Momenta In The Regions Of 1.45 And 1.7 Gev/C

The PS185 experiment at LEAR/CERN has investigated strangeness production in, (p) over barp collisions with final states such as (A) over bar Lambda, <()over bar>(0)A + c.c, <((+))over bar>Sigma (+),<((-))over bar>Sigma (-) and KSKS. Results are presented from a study of about 32000 KSKSX events obtained at several (p) over bar momenta in the regions of 1.45 and 1.7 GeV/c. The (p) over barp --> K(S)K(S)eta cross sections extracted at these momenta constitute the first measurement of this reaction in flight and are broadly consistent with expectations of a phase-space extrapolation of branching ratios from annihilation at rest.
