Abstract

Experimental data obtained recently have confirmed the predicted possibility for the appearance of a minimum in the behavior of the e⁺e⁻-annihilation into six pions near the threshold. From the theoretical analysis of the observed irregularity in the framework of a coupled channels model, the existence of a narrow vector state corresponding to 2³³S₁-state in the system with a mass of about 1800 MeV and a width of 15 MeV follows.
