Probing the onset of maximal entanglement inside the proton in diffractive deep inelastic scattering

M Hentschinski, DE Kharzeev, K Kutak, Z Tu - Physical Review Letters, 2023 - APS
It has been proposed that at small Bjorken x, or equivalently at high energy, hadrons
represent maximally entangled states of quarks and gluons. This conjecture is in accord with …
