Amplified Isospin Breaking from Coupled-Channel Dynamics Near Threshold

Xiang-Kun Dong, Feng-Kun Guo, Christoph Hanhart +2

We identify the dynamical origin of amplified isospin breaking in near-threshold states. Using a pole-residue-based measure defined directly from the pole couplings, rather than fr…

Vector charmonium(-like) states in the energy range of 4.1-4.6 GeV

Xiang-Kun Dong, Vadim Baru, Leon von Detten +5

The spectrum of vector charmonium(-like) states in the 4.1\dash4.6~GeV energy region exhibits a long-standing tension between inclusive and exclusive measurements. While the inclus…

Precise determination of the properties of $X (3872)$ and of its isovector partner $W_{c 1}$

Teng Ji, Xiang-Kun Dong, Feng-Kun Guo +2

We perform a simultaneous fit to BESIII data on $e^{+} e^{-} \to γ (D^{0} D ˉ^{0} π^{0} / J / ψ π^{+} π^{-})$ and LHCb data on $B^{+} \to K^{+} (J / ψ π^{+} π^{-})$ to precisely determine the properties of the $…

Dispersive analysis of the isospin breaking in the $X (3872) \to J / ψ π^{+} π^{-}$ and $X (3872) \to J / ψ π^{+} π^{0} π^{-}$ decays

Jorgivan Morais Dias, Teng Ji, Xiang-Kun Dong +5

We analyze the latest LHCb data on the $π^{+} π^{-}$ spectrum in the isospin-violating $X (3872) \to J / ψ π^{+} π^{-}$ decay, based on dispersion theory to deal with the $π π$ final state interac…

Predicting isovector charmonium-like states from X(3872) properties

Zhen-Hua Zhang, Teng Ji, Xiang-Kun Dong +4

Using chiral effective field theory, we predict that there must be isovector charmonium-like $D D ˉ^{*}$ hadronic molecules with $J^{P C} = 1^{++}$ denoted as $W_{c 1}$ . The inputs are…

Hints of the $J^{P C} = 0^{--}$ and $1^{--}$ $K^{*} K ˉ_{1} (1270)$ Molecules in the $J / ψ \to ϕ η η^{'}$ Decay

Xiang-Kun Dong, Teng Ji, Feng-Kun Guo +2

The primary objective of this study is to investigate hadronic molecules of $K^{*} K ˉ_{1} (1270)$ using a one-boson-exchange model, which incorporates exchanges of vector and pseudos…

Interactions of the Pseudoscalar Meson Octet and the Baryon Decuplet in the Continuum and a Finite Volume

Teng Ji, Xiang-Kun Dong, Ulf-G. Meißner

This study focuses on the interaction of the pseudoscalar meson octet and the baryon decuplet. In the continuum, it is observed that several $J^{P} = \frac{3}{2}^{-}$ baryon resonances can…

Understanding the $0^{++}$ and $2^{++}$ charmonium(-like) states near 3.9 GeV

Teng Ji, Xiang-Kun Dong, Miguel Albaladejo +4

We propose that the $X (3915)$ observed in the $J / ψ ω$ channel is the same state as the $χ_{c 2} (3930)$ , and the $X (3960)$ , observed in the $D_{s}^{+} D_{s}^{-}$ channel, is an $S$ -wave $D_s…

Establishing the heavy quark spin and light flavor molecular multiplets of the $X (3872)$ , $Z_{c} (3900)$ and $X (3960)$

Teng Ji, Xiang-Kun Dong, Miguel Albaladejo +3

Recently, the LHCb Collaboration reported a near-threshold enhancement, $X (3960)$ , in the $D_{s}^{+} D_{s}^{-}$ invariant mass distribution. We show that the data can be well described by e…

Prediction of a narrow exotic hadronic state with quantum numbers $J^{P C} = 0^{--}$

Teng Ji, Xiang-Kun Dong, Feng-Kun Guo +1

Lots of charmonium-like structures have been observed in the last two decades. Most of them have quantum numbers that can be formed by a pair of charm and anticharm quarks, thus it…
