Description
The Hamiltonian formalism is a particularly useful framework to describe hadron bound states in QCD while generating the Hilbert space in terms of their constituents. The quantum entropy of any bound state is zero, but when the proton components are probed, for example by deep inelastic scattering, the study of the entropy of entanglement between the components and the rest of the proton leads to new insights on the high energy scattering behavior of hadrons. In this talk we examine how the growth above the classical geometric cross section is directly related to the increase of the internal quantum entropy from the entangled parton distribution in hadrons. We will also briefly examine the connection between the scale dependence of the Pomeron from the QCD evolution of the gluon distribution function, the rising of the integrated cross section in photoproduction of vector mesons, hadron multiplicity and entropy as recently discussed in [1].
