Electromagnetic form factors of the nucleon
The European Physical Journal A, 2005The experimental and theoretical status of elastic electron scattering from the nucleon is reviewed. As a consequence of new experimental facilities and new theoretical insights, this subject is advancing with unprecedented precision.

Electromagnetic Form Factor of the Neutrinos
Physical Review Letters, 1963A zero-mass two-component theory for the neutrino and the existence of an intermediate boson W/sup plus or minus / are assumed. The scalar function, on which the matrix element of the electromagnetic current operator evaluated between states of a single neutrino depends, is calculated. A marked difference is found between the form factors, f(q/sup 2/),

Effective electromagnetic form factor of the neutrino
Physical Review D, 1989The conceptual difficulties affecting the definition of the neutrino electromagnetic form factor are briefly reviewed in the context of the standard model. It is then shown that the radiative corrections ${\ensuremath{\Delta}}^{(\ensuremath{\nu};l)}$(${q}^{2}$) and ${\ensuremath{\Delta}}^{(\ensuremath{\nu};h)}$(${q}^{2}$) relevant to \ensuremath{\nu ...

On the canonical form of the electromagnetic field
ANNALI DELL'UNIVERSITA' DI FERRARA, 2006Using the decomposition of an antisymmetric 2-tensor as a sum of two orthogonal bivectors, the various canonical forms of the electromagnetic tensor field are analyzed, recovering known results. However, introducing 1+3 spacetime splitting techniques, the canonical forms are associated to special frames and observers and this helps to clarify the role ...

Deuteron electromagnetic form factors
Il Nuovo Cimento, 1963Nous definissons les facteurs de forme electromagnetiques du deuteron correspondant aux distributions de charge, de moment quadrupolaire et de moment magnetique. L’approximation non relativiste de ces facteurs de forme est donnee en fonction de la partie isoscalaire des facteurs de forme du nucleon et de fonctions de structure reliees a la fonction d ...
