Abstract
An exotic meson, the
with
JPC=1-+,
has been seen to decay into a
p-wave
system.
If this decay conserves flavor
SU(3),
then it can be shown that this exotic meson must be a
four-quark state (
) belonging to
a flavor
representation of
SU(3). In contrast, the
with a substantial decay mode into
is likely to
be a member of a flavor octet.
