    • There is an interesting subtlety associated with this decomposition. Figure 2(b) includes time orderings in which the pair creation occurs before the annihilation (see Fig. 3) corresponding to meson loop processes. However, the complete set of meson loop processes produce not only Fig. 2(b) but also Z graphs of Fig. 2(a) and graphs with closed qq̄ loops inserted into Fig. 2(a). Thus a consistent treatment actually requires that S be not just the simple valence graph shown, but also include graphs with internal qq̄ loops [4].

    • 2 matrices should such an improvement be justified by an improvement in the relevant experimental data.

    • note
    • There is a loophole in this argument. It is possible that instead there could be a conspiracy between the hadronic loop processes and other sources of OZI violation.

    • N. Isgur, Phys. Rev. D ibid. 57, 4041 (1998).] We have found no other recent lattice measurements of these masses close to the chiral limit (see, however, Ref. [27]), or of other spectroscopic properties of the P-wave mesons, and consequently hope to report on their spectroscopy in a forthcoming publication. In any event, at the level of accuracy relevant to the results reported here, these 10% effects are not significant.
