Abstract

In this paper we address the (charge) longitudinal electromagnetic response for a homogeneous system of nucleons interacting via meson exchanges in the functional framework. This approach warrants consistency if the calculation is carried on order by order in the mesonic loop expansion with random-phase-approximation-dressed mesonic propagators. At the 1-loop order and considering π, ρ, and ω exchanges we obtain a quenching of the response, in line with the experimental results.
