Energy and electromagnetism of a differential k-form [PDF]
Journal of Mathematical Physics, 2012 Let X be a smooth manifold of dimension 1 + n endowed with a Lorentzian metric g. The energy tensor of a 2-form F is locally defined as \documentclass[12pt]{minimal}\begin{document}$T_{ab}\break := \, - \left( {F_a}^{i} F_{bi} - \frac{1}{4} \, F^{ij} F_{ij} g_{ab} \right)$\end{document}Tab:=−FaiFbi−14FijFijgab. In this paper we characterize this tensor

Use of form factors in electromagnetic interactions [PDF]
Physical Review C, 1989 We comment on the description of electromagnetic reactions involving hadrons, when the internal structure of the hadrons is taken into account. General off-shell vertex operators, only constrained by Lorentz and gauge invariance, are used. The electromagnetic production of pions on a nucleon is discussed as an example.

Electromagnetic form factors [PDF]
Il Nuovo Cimento, 1965 Les facteurs de forme physiques d’une particule de spinJ sont definis de facon, covariante en utilisant une representation d’helicite du courant electromagnetique dans le systeme de Breit. La forme generale de la section efficace non polarisee est donnee explicitement. La matrice densite est calculee dans le cas d’un spin J=3/2.
