Light-Baryon Spectroscopy and the Electromagnetic Form Factors in the Quark Model,formulated on the light-front, adopting a one-body current with constituent quark form factors. The results suggest that soft, non-perturbative effects can play a relevant role for explaining the existing data on elastic as well as transition form factors (at least) for .. ≲ 10 ÷ 20 (.)..

The Nucleon Wave Function in Light-Front Dynamics,ing any Melosh rotation matrices. It also reduces the calculations to the standard routine of the Dirac matrices and of the trace techniques. The importance of investigating the influence of the extra components on the observables is emphasized.

QCD Sum Rules and Soft-Hard Interplay for Hadronic Form Factors, at accessible momentum transfers. The “humpy” distribution amplitudes used to enhance hard terms cannot be derived from QCD sum rules in a self-consistent way. The estimates of soft terms obtained within the local quarkhadronic duality approach in all cases are close to existing data, providing an experimental evidence that hard terms are small.

Semirelativistic Constituent-Quark Model with Goldstone-Boson-Exchange Hyperfine Interactions,the version where the latter is represented by pseudoscalar meson exchange (π, ., η, η′) and restricted to the spin-spin component only a unified description of all light- and strange-baryon spectra is provided in close agreement with phenomenology. We discuss the extension of the model that include

Hypercentral Constituent Quark Model,ntial contributions. We report our results on the baryon spectrum, the helicity amplitudes and the transition form factors, comparing them with experimental data. The effect of introducing relativistic corrections at a kinematical level is also briefly discussed.
