The structure of the hadron resonances attracts much attention, in association with the
recent observations of various exotic hadrons which do not fit well in the conventional …

Resonant hadronic systems often exhibit a complicated decay pattern in which three-body
dynamics play a relevant or even dominant role. In this work we focus on the a 1 (1260) …

The structure of dynamically generated states in the chiral unitary approach is studied from a
viewpoint of their compositeness. We analyze the properties of bound states, virtual states …

We describe a symmetry-preserving calculation of the light-quark meson spectrum, which
combines a description of pion properties with reasonable estimates of the masses of …

Starting from the SU (3) limit, we consider the nature of the dynamically generated
resonances Λ (1380), Λ (1405) and Λ (1680) as the pion and kaon masses are tuned to their …

Masses, widths, and branching ratios of hadronic resonances are quantified by their pole
positions and residues with respect to transition amplitudes on the Riemann sheets of the …

We perform an analysis of the three-pion system with quantum numbers JPC= 1++ produced
in the weak decay of τ leptons. The interaction is known to be dominated by the axial meson …

Through the scattering of light-pseudoscalar mesons (π, K, η, η′) off charmed mesons (D, D
s), we study the D s 0*(2317) state and other relevant charm scalar mesons in a unitarized …

We study exotic mesons with double charm and bottom flavor (| C|=| B|= 2), whose quark
configuration is Q¯ Q¯ qq. This quark configuration has no annihilation process of quark and …

The axial-vector mesons a 1 (1260), b 1 (1235), f 1 (1285), h 1 (1170), h 1 (1380), and K 1
(1270) are dynamically generated in the unitized chiral perturbation theory. Such a picture …
