Electromagnetic form factors of the nucleon in spacelike and timelike regions
J. P. B. C. de Melo, T. Frederico, E. Pace +2
An approach for a unified description of the nucleon electromagnetic form factors in spacelike and timelike regions is presented. The main ingredients of our model are: a Mand…
Timelike and spacelike hadron form factors, Fock state components and light-front dynamics
E. Pace, G. Salme`, T. Frederico +2
A unified description of spacelike and timelike hadron form factors within a light-front model was successfully applied to the pion. The model is extended to the nucleon to study t…
Pole Approximation for the pion eletromagnetic form factor within light-front dynamics
J. P. B. C. de Melo, J. S. Veiga, T. Frederico +2
We carefully investigate the reliability of the propagator Pole Approximation, i.e, the approximation of retaining only the propagator in the evaluation of the Mandelstam covariant…
Electromagnetic Hadron Form Factors and Higher Fock Components
J. P. B. C. de Melo, T. Frederico, E. Pace +2
Investigation of the spacelike and timelike electromagnetic form factors of hadrons, within a relativistic microscopical model characterized by a small set of hypothesis, could she…
