Query: Systematics of oscillatory behavior in hadronic masses and widths   A systematic study of hadron masses and widths shows regular oscillations
that can be fitted by a simple cosine function. This property can be observed
when the difference between adjacent masses of each family is plotted versus
the mean mass.
