Abstract

A search has been made in neutron-beryllium interactions for neutral narrow enhancements produced at Feynman

x >~ 0.2

. Upper limits are presented for production cross-sections times branching ratio into the two-body channels

π^{+} π^{-}

,

π^{+} K^{-}

, and

p \bar{p}

for masses in the interval

2 GeV ≲ m ≲ 4 GeV

. Comparisons are made with

ψ

production observed in the same experiment.
