Evidence for an $ω π π$ Resonance in the $I = 1$ State at a Mass of 1695 MeV

Evidence is presented for the existence of a boson resonance with mass

M = 1695 \pm 20

MeV and width

Γ = 90 \pm 20

MeV. It decays principally into

ω ρ

and

ω π π

and has

G = - 1

and

I = 1

. This state can be interpreted either as a new resonance, further complicating the

R

region, or as an alternative decay of the

π (1640)

; the latter would require an

\frac{ω π π}{f π}

branching ratio greater than 4.
