Search forY2*Resonances

Abstract

A search has been made for a doubly charged $\Sigma \pi$ resonance produced in $\overline{K}N$ interactions. Data in hydrogen with incident $K^{-}$ momentum of 1.51 and 1.70 BeV/c, and in deuterium with a $K^{-}$ momentum of 1.49 BeV/c, show no evidence for any $T=2\mathrm{}$ resonance for a $\Sigma \pi$ mass below 1900 MeV.
