We construct a general QCD light front formalism to compute many-body color charge correlators in the proton. These form factors can be extracted from deeply inelastic scattering measurements of exclusive final states in analogy to electromagnetic form factors extracted in elastic electron scattering experiments. Particularly noteworthy is the potential to extract a novel odderon form factor, either indirectly from exclusive J/Psi measurements or directly from exclusive measurements of the eta(c) or tensor mesons at large Bjorken x. Besides the intrinsic information conveyed by these color charge correlators on the spatiotemporal tomography at the subfemtoscopic scale at large x, the corresponding cumulants extend the domain of validity of McLerran-Venugopalan type weight functionals from small x and large nuclei to nucleons and light nuclei at large x, as well as to nonzero momentum transfer. This may significantly reduce nonperturbative systematic uncertainties in the initial conditions for QCD evolution equations at small x and could be of strong relevance for the phenomenology of present and future collider experiments.
