Description

In the effective-mass spectrum of the KOSK+pπ-π- system produced in π-p interactions at 16 GeV/c, an enhancement is observed that suggests the existence of a narrow baryon state with M = 3521 ± 3 MeV/c2 and γ = 6+21-6 MeV/c2. Events in the peak region show special kinematic features at a probability level of 6.4 x 10 -9, which is comparable with that of the background. These features serve as additional evidence for the existence of a hypothetical baryon and are probably related to the properties of this baryon. 10 refs., 1 fig
