Light meson decays, care of Ted Barnes.
These tables are taken from T. Barnes, F.E. Close, P.R. Page, and E.S. Swanson Phys. Rev. D55, 4157 (1997). Please refer to this work if you use these tables in your research.
We quote numerical values for partial widths predicted
by the 3P0 model. The masses used are experimental values of well
established candidates, usually taken from the 1996 PDG,
otherwise we used an approximate
multiplet mass.
These are 1750 MeV (2P), 1670 MeV (1D), 2050
MeV (1F), and 1900 MeV and 1800 MeV respectively for the
33S1 and
3S0. Although we found optimum parameters near
and
GeV in a fit to light 1S and 1P
decays, these parameters
lead to moderate overestimates of the widths of the well established
higher-L states
and f4(2044); with this
a value
closer to
is preferred.
Consequently we quote widths for all
these higher quarkonia with the parameters

The tables are largely self explanatory. Except in a few cases the states are specified uniquely by their labels. Exceptions are the and , which we take to be the usual combinations of and basis states. We assume that the and are pure states. The strange mesons K1(1273) and K1(1402) are taken to be the linear combinations

The tables give partial widths for all nonstrange 2S, 3S, 2P, 1D and 1F quarkonia to all two-body modes allowed by phase space, rounded to the nearest MeV. The predictions of the dominant modes of the ``missing states'' in the quark model, such as the 2- states and most of the 1F states, are especially interesting. If the 3P0 model has even moderate accuracy these tables should be very useful in searches for these states.
