Description
The first excited state of the nucleon dominates many nuclear phenomena at energies above the pion-production threshold and plays a prominent role in the physics of the strong interaction. The study of the N to $\Delta$ transition form factors (TFFs) allows to shed light on key aspects of the nucleonic structure that are essential for the complete understanding of the nucleon dynamics. In this talk we will discuss collected and proposed measurements of the TFFs in Hall C at JLab, utilizing the SHMS and the HMS spectrometers, that focus on low four-momentum transfer squared where the mesonic cloud dynamics are dominant and rapidly changing. Possible future experiments pursuing bound neutron excitation with the CLAS12 and ALERT detectors, as well as large Q$^2$ measurements with the SoLID detector and beam energy upgrades at JLab, will also be discussed.
