Decomposition of the axial-vector current in a finite box
Felix Hermsen, Matthias F. M. Lutz, Rob G. E. Timmermans
We consider the matrix element of the axial-vector current between two nucleon states in a finite box. Starting from the chiral Lagrangian density with nucleon and Delta-isobar deg…
Chiral symmetry, strangeness and resonances
M. F. M. Lutz, E. E. Kolomeitsev, C. L. Korpa
We review the important role played by the chiral SU(3) symmetry in predicting the properties of antikaons and hyperon resonances in cold nuclear matter. Objects of crucial importa…
Quark-mass dependence of baryon resonances
M. F. M. Lutz, C. García-Recio, E. E. Kolomeitsev +1
We study the quark-mass dependence of J^P = \frac12^- s-wave and J^P = \frac32^- d-wave baryon resonances. Parameter-free results are obtained in terms of the leading order chiral…
Charmed meson resonances from chiral coupled-channel dynamics
E. E. Kolomeitsev, M. F. M. Lutz
Charmed meson resonances with quantum numbers J^P=0^+ and J^P=1^+ are generated in terms of chiral coupled-channel dynamics. At leading order in the chiral expansion a parameter-fr…
Open-charm meson resonances with negative strangeness
J. Hofmann, M. F. M. Lutz
We study heavy-light meson resonances with quantum numbers J^P=0^+ and J^P=1^+ in terms of the non-linear chiral SU(3) Lagrangian. Adjusting the free parameters that arise at suble…
On charm baryon resonances and chiral symmetry
M. F. M. Lutz, E. E. Kolomeitsev
We study heavy-light baryon resonances with quantum numbers J^P=1/2^- in terms of the non-linear chiral SU(3) Lagrangian. Within the chi-BS(3) approach a parameter-free leading ord…
