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…
Light vector hybrid states via QCD sum rules
Feng-Kun Guo, Peng-Nian Shen, Zhi-Gang Wang +2
Vector hybrid states with light quarks are investigated via QCD sum rules. The results show that the masses of the , , and st…
