Observation in the $K^{+}K^{-}$ system of a new structure at 2.20 GeV

A sample of 56909 events of the reaction pi /sup -/p to K/sup +/K/sup -/n at 10 GeV/c has been measured in the Omega spectrometer at CERN. In the K/sup +/K/sup -/ system, besides production of mesons in the S* / phi , f/sup 0//A/sub 2/, g/ omega * and h regions the authors observe a new structure at...

Descripción
Sumario:A sample of 56909 events of the reaction pi /sup -/p to K/sup +/K/sup -/n at 10 GeV/c has been measured in the Omega spectrometer at CERN. In the K/sup +/K/sup -/ system, besides production of mesons in the S* / phi , f/sup 0//A/sub 2/, g/ omega * and h regions the authors observe a new structure at 2.20 GeV with a width of the order of 200 MeV.
