Abstract

We report evidence for the existence of a charged narrow state of mass M ∼ 2.02 GeV/c² and widtt Γ {less-than or approximate} 0.04 GeV/c², decaying into N N ̄. The state is observed in the reaction pp→p_fastnπ⁺π^-π^- at 6 GeV/c and in pp→π_fast ⁺pnπ⁺π^- at 9 GeV/c in a triggered bubble chamber experiment at the SLAC Hybrid Facility.
