Definition of gravitational local spatial densities for spin-0 and spin-1/2 systems
J. Yu. Panteleeva, E. Epelbaum, J. Gegelia +1
We work out details of defining the spatial densities corresponding to the gravitational form factors of spin-0 and spin-1/2 systems using spherically symmetric sharply localized w…

On the definition of electromagnetic local spatial densities for composite spin- systems
J. Yu. Panteleeva, E. Epelbaum, J. Gegelia +1
An unambiguous definition of the electromagnetic spatial densities for a spin-1/2 system is proposed and worked out in the zero average momentum frame and in moving frames. The obt…
