Scattering lengths of strangeness S=-2 baryon-baryon interactions
A. M. Gasparyan, J. Haidenbauer, C. Hanhart
We reconsider a method based on dispersion theory, that allows one to extract the scattering length of any two-baryon system from corresponding final-state interactions in producti…
Remarks on the quantum numbers of X(3872) from the invariant mass distributions of the rho J/psi and omega J/psi final states
C. Hanhart, Yu. S. Kalashnikova, A. E. Kudryavtsev +1
We re-analyse the two- and three-pion mass distributions in the decays X(3872)->rho J/psi and X(3872)->omega J/psi and argue that the present data favour the 1++ assignment for the…
Pion photoproduction in a dynamical coupled-channels model
F. Huang, M. Döring, H. Haberzettl +5
The charged and neutral pion photoproduction reactions are investigated in a dynamical coupled-channels approach based on the formulation of Haberzettl, Huang, and Nakayama [Phys.…
Dynamical coupled-channels model study of pion photoproduction
F. Huang, M. Döring, H. Haberzettl +5
The photoproduction of pion off nucleon is investigated within a dynamical coupled-channels approach based on the Juelich pi-N model, which has been quite successful in the descrip…
Three-body dynamics for the X(3872)
V. Baru, C. Hanhart, A. A. Filin +3
We investigate the role played by the three-body dynamics on the near-threshold resonance X(3872) charmonium state, which is assumed to be formed by nonperturbative $D\…
Model-independent approach to eta -> pi+ pi- gamma and eta' -> pi+ pi- gamma
F. Stollenwerk, C. Hanhart, A. Kupsc +2
We present a new, model-independent method to analyze radiative decays of mesons to a vector, isovector pair of pions of invariant mass square below the first significant pion-pion…
