Abstract | Chin. Phys. C, 2017, 41(1): 013103 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
$\bar{D}^{0}D^{0*}$ 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 $3872$ MeV by introducing another parameter $I_{0}$ that
changes the strength of the interaction in this one component of $X(3872)$. The
revised value of this second parameter can guide future trends in modeling of
the full exotic meson $X(3872)$. We also report the changes with $I_{0}$ in the
$S$-wave spin averaged cross sections for
$\bar{D}^{0}D^{0*}\longrightarrow\omega J/\psi$ and
$\bar{D}^{0}D^{0*}\longrightarrow\rho J/\psi$. These cross sections are
important regarding the study of QGP (quark gluon plasma). |
