Mass splittings within heavy baryon isospin multiplets in chiral perturbation theory
Feng-Kun Guo, Christoph Hanhart, Ulf-G. Meißner
We calculate the mass splittings within the heavy baryon isospin multiplets Σ_{c(b)} and Ξ_{c(b)}' in chiral perturbation theory to leading one-loop order. The pattern of the mass…
Subleading contributions to the width of the D_{s0}*(2317)
Feng-Kun Guo, Christoph Hanhart, Siegfried Krewald +1
We construct the effective chiral Lagrangian involving the D--mesons and Goldstone bosons at next-to-leading order taking into account strong as well as electromagnetic interaction…
Evidence that the Y(4660) is a f_0(980)psi' bound state
Feng-Kun Guo, Christoph Hanhart, Ulf-G. Meißner
We demonstrate that the experimental information currently available for the Y(4660) is consistent with its being a f_0(980)psi' molecule. Possible experimental tests of our hypoth…
Hadronic-loop induced mass shifts in scalar heavy-light mesons
Feng-Kun Guo, Siegfried Krewald, Ulf-G. Meissner
We calculate the mass shifts of heavy-light scalar mesons due to hadronic loops under the assumption that these vanish for the groundstate heavy-light mesons. The results show that…
Hyperon decay form factors in chiral perturbation theory
Andre Lacour, Bastian Kubis, Ulf-G. Meißner
We present a complete calculation of the SU(3)-breaking corrections to the hyperon vector form factors up to O(p^4) in covariant baryon chiral perturbation theory. Partial higher-o…
Model-independent extraction of two-photon effects in elastic electron-proton scattering
M. A. Belushkin, H. -W. Hammer, U. -G. Meißner
We address the discrepancy between the Rosenbluth and polarization transfer data for the electromagnetic form factors of the nucleon. Assuming that the effect of two-photon correct…
