The observed charmed hadron and the interaction
In this work, we systematically study the interaction of and nucleon,
which is stimulated by the observation of close to the
threshold of . Our numerical result obtained by the dynamical
investigation indicates the existence of the systems with
, which not only provides valuable information to
understand the underlying structure of but also improves
our knowledge of the interaction of and nucleon. Additionally, the bottom
partners of the systems are predicted, which might be as one of the
tasks in LHCb experiment.Comment: 8 pages, 6 Figures. Accepted for publication in Phys. Rev.
A novel explanation of charmonium-like structure in
We first present a non-resonant description to charmonium-like structure
in the invariant mass spectrum of the process. The structure is depicted well by the
interference effect of the production amplitudes of via the intermediate charmonia and direct
annihilation into . This fact shows that
is not a genuine resonance, which naturally explains why
was only reported in its hidden-charm decay channel and
was not observed in the exclusive open-charm decay channel or -value scan.Comment: 4 pages, 1 table, 2 figures. Accepted for publication in Phys. Rev.
Prediction of a missing higher charmonium around 4.26 GeV in family
Inspired by the similarity of mass gaps of and families,
the prediction of missing higher charmonium with mass MeV and very
narrow width is made. In addition, the properties of two charmonium-like
states, and , and charmonium are discussed.
Here, as is established while the explanation of
to be is fully excluded and is typically a
very narrow state. These predictions can be accessible at BESIII, Belle and
BelleII in near future.Comment: 5 pages, 5 figures and 1 table. More discussions added. Accepted by
Eur. Phys. J.
