Baryon Form Factors

Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. Meißner

We review the status of baryon form factors with a special focus on the nucleon electromagnetic form factors which are known best. First, we give an introduction into the dispersiv…

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…

The Proton Charge Radius from Dimuon Photoproduction off the Proton

Yong-Hui Lin, Feng-Kun Guo, Ulf-G. Meißner

We investigate the feasibility of measuring the proton charge radius through dimuon photoproduction off a proton target. Our findings indicate that the Bethe-Heitler mechanism, whi…

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…
