Contribution to meson spectrscopy from central production

Mass spectra from two−body final state production due to pi−p, Kp, and pp annihilation at 85 GeV/c has been measured. Bumps in pi−plus−pi−minus spectra peak at ‐934 MeV with width of ‐77 MeV. Interesting features are present in K−plus−K−minus and K1−neutral−K1−neutral spectra.
