The spectrum of hadrons is the manifestation of color confinement of quantum
chromodynamics. Hadronic resonances correspond to poles of the S-matrix. Since 2003 …

The existence and properties of the sigma meson have been controversial for almost six
decades, despite playing a central role in the spontaneous chiral symmetry of QCD or in the …

We consider the D¯(*) Σ c (*) states, together with J/ψ N and other coupled channels, and
take an interaction consistent with heavy quark spin symmetry, with the dynamical input …

The Λ (1405) baryon resonance plays an outstanding role in various aspects in hadron and
nuclear physics. It has been considered that the Λ (1405) resonance is generated by the …

The interactions of D̄ Σ c-D̄ Λ c, D̄* Σ c-D̄* Λ c, and related strangeness channels, are
studied within the framework of the coupled-channel unitary approach with the local hidden …

We review recent progress in the investigation of the electroexcitation of nucleon
resonances, both in experiment and in theory. We describe current experimental facilities …

We present results on the electroexcitation of the low mass resonances Δ (1232) P 33, N
(1440) P 11, N (1520) D 13, and N (1535) S 11 in a wide range of Q 2. The results were …

We explore the consequences of heavy quark spin symmetry for the charmed meson-
antimeson system in a contact-range (or pionless) effective field theory. As a trivial …

Elastic πN scattering and the world data of the family of reactions π− p→ ηn, K 0 Λ, K 0 Σ 0,
K+ Σ−, and π+ p→ K+ Σ+ are described simultaneously in an analytic, unitary, coupled …
