In the line of PAC46 recommendations, we wish to propose to PAC48 indisputable high-impact physics case experiments supporting the development of polarized positron beams at CEBAF. With the expectation of significant experimental signals and a strong physics output, deeply virtual Compton scattering off the proton (p-DVCS) is the golden physics case for positron beams. Based on the PAC46 Letter-of-Intent, we consequently intend to submit two proposals: high precision mesurements of selected unpolarized cross sections with the NPS (Neutral Photon Spectrometer) in Hall C, and a wide kinematical survey of moderate precisions measurements of cross sections and beam spin asymmetries with CLAS12.
