Abstract

A

J^{PC} = 0^{+ +}

{K_{1}}^{0} {K_{1}}^{0}

enhancement at a mass of 1030±10 MeV with a width of

45_{- 15}^{+ 35}

MeV is observed in

\bar{K} N

interactions. An

s

-wave resonance interpretation of this enhancement is favored over an

s

-wave scattering length effect. Within experimental uncertainties, we associate this enhancement with the

S^{*}

observed in

π^{-} p

interactions.
