On the narrow dip structure at 1.9 GeV/c2 in diffractive photoproduction

/ Abstract
Abstract The narrow dip observed at 1.9 GeV/ c 2 by the Fermilab experiment E687 in diffractive photoproduction of 3 π + 3 π − 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.
