Indication of existence of a narrow baryon resonance with mass 1. 95 GeV/c/sup 2/

1981

An experiment carried out in the neutron beam of the Serpukhov accelerator has yielded an indication of the production of a new resonance with mass 1.95 GeV/c/sup 2/ and width not exceeding 0.015 GeV/c/sup 2/, which decays into ..sigma../sup -//sub 1385/ and K/sup +/.
