We study the possible heavy molecular states composed of a pair of charm mesons in the H and S doublets. Since the P-wave charm-strange mesons Ds0(2317) and Ds1(2460) are extremely narrow, the future experimental observation of the possible heavy molecular states composed of $D_{s}/D_{s}^{\ast}$ and Ds0(2317)/Ds1(2460) may be feasible if they really exist. Especially the possible JPC=1−− states may be searched for via the initial state radiation technique.

The molecular assignments to the three Pc states and the similar production mechanism between the Λb → Pc + K and B → XY Z + K convince us the B decaying to a charmonium state plus light mesons couldExpand
Predictions of the hidden-charm molecular states with the four quark components
In this work, we study the $$T\bar{T}$$TT¯-type molecular systems systematically via the one pion exchange model, where T denotes the narrow $$J^P=1^+$$JP=1+$$D_1$$D1 meson or $$2^+$$2+$$D_2^*$$D2∗Expand
The hidden-charm pentaquark and tetraquark states
In the past decade many charmonium-like states were observed experimentally. Especially those charged charmonium-like $Z_c$ states and bottomonium-like $Z_b$ states can not be accommodated within theExpand

The confirmation of charged charmonium-like states indicates that heavy quark molecules should exist. Here we discuss the possibility of a molecule state with J PC =3 −+ . In a one-boson-exchangeExpand
Possible hidden-charm molecular baryons composed of an anti-charmed meson and a charmed baryon
Using the one-boson-exchange model, we studied the possible existence of very loosely bound hidden-charm molecular baryons composed of an anti-charmed meson and a charmed baryon. Our numericalExpand
The discovery of numerous new charmonium-like structures since 2003 have revitalized interest in exotic meson spectroscopy. These structures do not fit easily into the conventional charmonium model,Expand
The open-charm radiative and pionic decays of molecular charmonium Y(4274)
In this work, we investigate the decay widths and the line shapes of the open-charm radiative and pionic decays of Y(4274) with the $D_{s}\bar{D}_{s0}(2317)$ molecular charmonium assignment. OurExpand
Novel charmonium-like structures in the J / ? ? and J / ? ? invariant mass spectra
Abstract Stimulated by the new evidence of Y ( 4274 ) observed in the J / ψ ϕ invariant mass spectrum, we first propose the charmonium-like state Y ( 4274 ) as the S-wave D s D ¯ s 0 ( 2317 ) + h.c.Expand

Possibility of deeply bound hadronic molecules from single pion exchange.

Estimating mass of σ-meson and study on application of the linear σ-model
