Predictions of the hidden-charm molecular states with four-quark component
In this work, we study the -type molecular systems systematically
via one pion exchange model, where denotes the narrow meson
or meson and is its antiparticle. With the effective
potentials, we try to find the bound state solutions of the corresponding
systems, which provide crucial information of whether there exist the
-type molecular states. According to our analysis, we predict some
-type molecular states which may be accessible at future experiments
like LHCb and forthcoming BelleII.Comment: 13 pages, 2 figures and 8 tables. Accepted by Eur. Phys. J.
A review of the open charm and open bottom systems
Since the discovery of the first charmed meson in 1976, many open-charm and
open-bottom hadrons were observed. In 2003 two narrow charm-strange states
and were discovered by the BaBar and CLEO
Collaborations, respectively. After that, more excited heavy hadrons were
reported. In this work, we review the experimental and theoretical progress in
this field.Comment: Review accepted by Reports on Progress in Physics, 161 pages, 53

Triply heavy tetraquark states with the configuration
In the framework of the color-magnetic interaction, we systematically
investigate the mass splittings of the tetraquark states and
estimated their rough masses in this work. These systems include the explicitly
exotic states and and the hidden exotic
states , , , and
. If a state around the estimated mass region could be
observed, its nature as a genuine tetraquark is favored. The strong decay
patterns shown here will be helpful to the experimental search for these exotic
states.Comment: 14 pages, 3 figures and 9 tables. Accepted by Eur. Phys. J.
