Investigation of resonance structures in the system of two KS-mesons in the mass regions around 1595 MeV

This report is devoted to previously unknown narrow resonance in the KSKS-system that is observed in experimental data coming from 6-m spectrometer (MIS ITEP). The experimental data on the production of KS pair were obtained in π-p interaction at 40 GeV by using a neutral trigger. In the KSKS-system a maximum of width <3 MeV is observed at mass of about 1595 MeV. The statistical confidence of this state is better than 6 standard deviations. Spin-parity of the state X(1595) is preferably JPC 2++. Seeing its very small width this resonance is likely to be cryptoexotics (see [1],[2] for details). (author)
