System in QCD-Improved Many Body Potential
For a system of current interest (composed of charm, anticharm quarks and a
pair of light ones), we show trends in phenomenological implications of
QCD-based improvements to a simple quark model treatment. We employ resonating
group method to render this difficult four-body problem manageable. We use a
quadratic confinement so as to be able to improve beyond the Born
approximation. We report the position of the pole corresponding to
molecule for the best fit of a model parameter to the
relevant QCD simulations. We point out the interesting possibility that the
pole can be shifted to MeV by introducing another parameter that
changes the strength of the interaction in this one component of . The
revised value of this second parameter can guide future trends in modeling of
the full exotic meson . We also report the changes with in the
-wave spin averaged cross sections for
and
. These cross sections are
important regarding the study of QGP (quark gluon plasma).Comment: It is to be published in Chinese Physics
