Description

Recently observed hadrons that do not fit into the ''normal'' spectroscopic order should have been produced in old experiments. Are these claims supported by the legacy data? Fermilab Experiment 690 collected a 5 x 10{sup 9} event sample of p+p{yields} p{sub f}+X events at a beam momentum of 800 GeV/c ({radical}s = 38.8 GeV) at Lab G in the Neutrino-East beam line in the Tevatron 1991 fixed target run. The detector was an open geometry magnetic spectrometer with large geometric acceptance and extremely good momentum resolution.
