Query: Chiral Extrapolations and Exotic Meson Spectrum   We examine the chiral corrections to exotic meson masses calculated in
lattice QCD. In particular, we ask whether the non-linear chiral behavior at
small quark masses, which has been found in other hadronic systems, could lead
to large corrections to the predictions of exotic meson masses based on linear
extrapolations to the chiral limit. We find that our present understanding of
exotic meson decay dynamics suggests that open channels may not make a
significant contribution to such non-linearities whereas the virtual, closed
channels may be important.
