On the narrow dip structure at 1.9 GeV/c$^2$ in diffractive photoproduction
Abstract
Description
The narrow dip observed at 1.9 GeV/c$^2$ by the Fermilab experiment E687 in diffractive photoproduction of $~3π^+3π^-$ is examined. The E687 data are refitted, a mechanism is proposed to explain why this resonance appears as a dip, and possible interpretations are discussed.
