Recent high-energy scattering data reveal that entropy-based observables offer a powerful new lens on the dynamics of hadron structure and particle production. In this talk, I present a unified framework in which scaling entropy derived from charged hadron multiplicity distributions and partonic transverse momentum fluctuations exposes a universal behavior across deep inelastic scattering and proton–proton collisions at the LHC. By analyzing entropy as a function of Bjorken-$x$, we determine the growth rate parameter $ \lambda $, which is directly linked to the Pomeron intercept in Regge-inspired QCD evolution. This approach not only provides a precise extraction of the intercept but also demonstrates the breakdown of traditional KNO scaling in favor of a more fundamental diffusion scaling associated with gluon dynamics. We find that the entropy growth is consistent across experiments and energy scales, supporting its interpretation as a robust initial-state observable.
