We report on recent nonperturbative techniques that combine the information of chiral
Lagrangians (with and without resonances) with unitarity in coupled channels and other …

We review the theory of hadronic atoms in QCD+ QED, based on a non-relativistic effective
Lagrangian framework. We first provide an introduction to the theory, and then describe …

The process γp→ K+ Λ is studied in a phenomenological approach. A thorough analysis of
the existing differential cross section data up to 1.4 GeV, taking into account the systematic …

A formalism, based on an isobaric approach using Feynman diagrammatic techniques,
which includes the nucleonic (spin≤ 5/2), hyperonic (spin 1/2), and kaonic resonances, is …

By using the non-relativistic effective Lagrangian approach to bound states, a complete
expression for the isospin-breaking corrections to the energy levels and the decay widths of …

Using our previously developed crossing and duality consistent model for kaon
photoproduction and radiative capture, we investigate the kaon electroproduction processes …

Previous approaches to the photoproduction and electroproduction of strangeness off the
proton, based upon effective hadronic Lagrangians, are extended here to incorporate the so …

The electromagnetic decays of the Σ 0 (1385) and Λ (1520) hyperons were studied in photon-
induced reactions γ p→ K+ Λ (1116) γ in the Large Acceptance Spectrometer detector at the …

We report a comprehensive analysis of the crossing related reactions p (γ, K+) Y and p (K−,
γ) Y for Y= Λ, Σ 0, and Λ (1405). Our model, which incorporates both crossing and duality …

The photoproduction reaction of γ p→ K+ Λ (1405) is investigated based on an effective
Lagrangian approach at the tree-level approximation with the purpose of understanding the …
