Description
Using the UA5 detector, the inclusive central production of Ksub(S)0 and Ksup(+-) mesons has been measured in non-single-diffractive interactions at the CERN SPS anti pp Collider at a c.m. energy of 540 GeV. The average transverse momentum is found to be =0.57+-0.03 GeV/c in the rapidity range vertical strokeyvertical stroke<2.5, which is an increase of about 30% over the top ISR energy. The K/π ratio has increased from about 8% at ISR energies to 9.5+-0.9+-0.7% (the last error is systematic) at 540 GeV. The average number of Ksub(S)0 per non-single-diffractive event is 1.1+-0.1 and the inclusive inelastic cross section is estimated at 49+-5 mb. (orig.)
