Evidence for a narrow dip structure at 1.9 GeV/c2 in 3π+ 3π- diffractive photoproduction
E687 Collaboration, P. L. Frabetti
Abstract
A narrow dip structure has been observed at 1.9 GeV/c2 in a study of diffractive photoproduction of the ~3π+3π- final state performed by the Fermilab experiment E687.
