Up to now, only resonances with $J^{PC}=1^{--}$ have been observed in
electron-positron annihilation, while $C=+1$ resonances appear only
among the decay products. The direct production of $1^{++}$ states
could happen through two virtual photon. Due to the smallness, this
process has never been verified experimentally. Given the high luminosity
at the BESIII experiment, a search of...

We measure the mass difference, $\Delta m_+$, between the $D^{*}(2010)^+$ and the $D^+$, using the decay chain $D^{*}(2010)^+ \to D^+ \pi^0 $ with $D^+ \to K^- \pi^+ \pi^+$. The data were recorded with the BaBar detector at center-of-mass energies at and near the $\Upsilon(4S)$ resonance, and correspond to an integrated luminosity of approximately $468 \, \mbox{fb}^{-1}$.
We measure...

The number of exotic candidates which are beyond the conventional quark model has grown dramatically during the last decades. Some of them could be viewed as analogues of the deuteron. Similarly, the existence of the triton indicates that bound states formed by three hadrons could also exist. To illustrate this possibility, we study the $DD^{\ast}K$ and $BB^{\ast}\bar{K}$ systems by using...

We extract the mass spectra of triply heavy charm-beauty baryons using Hypercentral constituent quark model. The first order correction is also added to the potential term of Hamiltonian. The radial and orbital excited state masses are also determined. Moreover, the Regge trajectories and magnetic moments are also given for these baryons.

We systematically investigate the weak decays of the doubly charmed baryons, which are helpful for experimental searches for these particles. The branching fractions are studied under the factorization hypothesis for the short-distance contributions and considering the rescattering effect for the long-distance contributions which are significantly enhanced. Comparing all the decay modes, we...

Understanding the hadron spectrum is one of the premier challenges in particle
physics. For a long time, the quark model has served as an
ordering scheme and brought systematics into the hadron zoo.
However, many new hadrons that were observed since 2003, including the
lowest-lying positive-parity charm-strange mesons
$D_{s0}^*(2317)$ and $D_{s1}(2460)$,
do not conform with quark...

We perform an analysis of QCD lattice data on charmed meson masses. The quark-mass dependence of the data set is used to gain information on the size of counter terms of the chiral Lagrangian formulated with open-charm states with $J^P = 0^-$ and $J^P = 1^-$ quantum numbers. Of particular interest are those counter terms that are active in the exotic flavour sextet channel. A chiral expansion...
