Search for Narrow Two-Body Enhancements at Fermilab

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 pp¯ for masses in the interval 2 GeV≲m≲4 GeV. Comparisons are made with ψ production observed in the same experiment.
