Determination of the entanglement entropy in elastic scattering using model-independent method for hadron femtoscopy

The entanglement entropy of two-body elastic scattering at high energies is studied by using the model-independent L'evy imaging method for investigating the hadron structure. It is considered the finite entropy in the momentum Hilbert space properly regularized and results are compared to recent evaluation using the diffraction peak approximation. We present the entropy for RHIC, Tevatron and LHC energies pointing out the underlying uncertainties.
