Hg. Blundell et S. Godfrey, XI(2220) REEXAMINED - STRONG DECAYS OF THE 1-F-3(2) AND 1-F-3(4) S(S)OVER-BAR MESONS, Physical review. D. Particles and fields, 53(7), 1996, pp. 3700-3711
We calculate the decay widths of the 1 F-3(2) and 1 F-3(4) <s(s)over b
ar> mesons and compare them to the measured properties of the xi(2220)
[now known as the f(4)(2220)]. Including previously neglected decay m
odes we find that the width of the F-3(2) state <s(s)over bar> meson i
s much larger than previously believed, making this explanation unlike
ly. On the other hand the predicted width of the F-3(4) state, althoug
h broader than the observed width, is consistent within the uncertaint
ies of the model. This interpretation predicts large partial widths to
KK(892) and K*(892)K*(892) final states which should be looked for.
A second possibility that would account for the different properties o
f the xi(2220) seen in different experiments is that two hadronic stat
es exist at this mass. The first would be a broader F-3(4) <s(s)over b
ar> State which is seen in hadron beam experiments while the second wo
uld be a narrow state with high glue content seen in the gluon rich J/
psi, radiative decay. Further experimental results are needed to sort
this out.
