Abstract

A sample of 56 909 events of the reaction π−p→K+K−n at 10 GeV/c has been measured in the Omega Spectrometer at CERN. In the K+K− system, besides production of mesons in the S ∗ /φ, f 0 / A 2 , g /ω ∗ and h regions we observe a new structure at 2.20 GeV with a width of the order of 200 MeV.
