Table 6: Meson-to-Meson and Meson-to-Baryon processes for and mesonic states, where and . Similar transitions can be obtained for the charge conjugated processes involving . Assuming that the cross-sections for all the transitions are of the same order of magnitude, Meson-to-Baryon processes to states are more likely than those involving and in the final state.
