Hidden gauge formalism for the radiative decays of axial-vector mesons
H. Nagahiro, L. Roca, A. Hosaka +1
The radiative decay of the axial-vector resonances into a pseudoscalar meson and a photon is studied using the vector meson Lagrangian obtained from the hidden gauge symmetry (HGS)…
Chiral Unitary Dynamics of Hadrons and Hadrons in a Nuclear Medium
E. Oset, L. S. Geng, D. Gamermann +7
In this talk I summarize recent findings around the description of axial vector mesons as dynamically generated states from the interaction of pseudoscalar mesons and vector mesons…
Two photons into π^0π^0
J. A. Oller, L. Roca
We perform a theoretical study based on dispersion relations of the reaction γγ\to π^0π^0 emphasizing the low energy region. We discuss how the f_0(980) signal emerges in γγ\to ππw…
On the role of meson loops in the decay into
H. Nagahiro, L. Roca, E. Oset +1
We investigate the relevance of the meson loops in the scalar meson decay into one photon and one vector meson, (, and ). In particular we estimate the size o…
Lambda(1405) in chiral SU(3) dynamics
Tetsuo Hyodo, Wolfram Weise, Daisuke Jido +2
We discuss several aspects of the Lambda(1405) resonance in relation to the recent theoretical developments in chiral dynamics. We derive an effective single-channel KbarK N intera…
Meson loops in the and radiative decays into ,
H. Nagahiro, L. Roca, E. Oset
We calculate the radiative decay widths of the and scalar mesons into and considering the dynamically generated nature of these scalar resonances wi…
