[NT/RBRC seminar] Revisiting the concept of relativistic charge distribution

by Cédric Lorcé (CPHT - Ecole Polytechnique)




We review and revisit the concept of charge distribution in the
relativistic context. Adopting a phase-space perspective allows us to
discuss the momentum dependence of these distributions and to connect the
well-known pictures in both the Breit frame and the infinite-momentum
frame. In particular, we explain why the center of the neutron charge
distribution appears to be negative in the infinite-momentum frame and
positive in the Breit frame.
