High precision measurements of the proton Generalized Polarizabilities at Jefferson Lab*

The Generalized Polarizabilities (GPs) are fundamental properties of the nucleon. They characterize the nucleon's response to an applied electromagnetic field, offering access to the polarization densities inside the nucleon, and as such they represent an essential part for a complete understanding of the nucleon structure and dynamics. The GPs can be explored through the measurement of the Virtual Compton Scattering reaction. Previous measurements of the proton electric GP at intermediate four-momentum transfer squared have challenged the predictions of theoretical calculations, raising questions in regard to the underlying reasons responsible for a local enhancement of the electric GP. The measurement of the magnetic GP, on the other hand, allows to quantify the interplay of the paramagnetism and diamagnetism inside the proton. The VCS experiment (E12-15-001) at JLab has accessed the proton GPs with high precision in the intermediate four-momentum transfer squared region, namely from Q2=0.3 (GeV2) to Q2=0.7 (GeV2). Preliminary results from the Hall C VCS experiment will be presented and future prospects will be discussed in this talk.
