Light Quark Spectroscopy Results from FOCUS and E687
Abstract
Using the FOCUS spectrometer (experiments 687 and 831 at Fermilab) we confirm the existence of a diffractively photoproduced enhancement in K+K- at 1750 with nearly 100 times the statistics of previous experiments. We also observe a narrow dip structure at 1.9 GeV/c2 in a study of diffractive photoproduction of the 3π+3π- final state.
