We present the global relativistic folding optical potential (GRFOP) fits to elastic proton scattering data from C-12 nucleus at energies between 20 and 1040 MeV. We estimate observables, such as the differential cross section, the analyzing power, and the spin rotation parameter, in elastic proton scattering within the relativistic impulse approximation. The new GRFOP potential is employed within the relativistic Green's function model for inclusive quasielastic electron scattering and for (anti) neutrino-nucleus scattering at MiniBooNE kinematics.engjournal articlehttp://dx.doi.org/10.1103/PhysRevC.94.014608http://journals.aps.org/open access539.1Electron nucleus scatteringProton elastic scatteringLorentz covariant representationNeutrino cross sectionsFinal state interactionNn interactionImpulse approximationPolarized protonsField-theoryC-12.Física nuclear2207 Física Atómica y Nuclear
