Schwinger-based QCD formulation's derivation of elastic pp scattering

Using previously described functional techniques for some non-perturbative, gauge invariant, renormalized QCD processes, a simplified version of the amplitudes - in which forms akin to Pomerons naturally appear - provides fits to ISR and LHC-TOTEM pp elastic scattering data. Those amplitudes rely on a specific function $\varphi (b)$ which describes the fluctuations of the transverse position of quarks inside hadrons.
