Abstract
With the aim at quantitatively investigating the longstanding problem concerning the effect of short-range nucleon-nucleon correlations on scattering processes at high energies, the total neutron-nucleus cross section is calculated within a parameter-free approach which, for the first time, takes into account, simultaneously, central, spin, isospin, spin-isospin, and tensor nucleon-nucleon correlations, and Glauber elastic and Gribov inelastic shadowing corrections. Nuclei ranging from $^{4}\mathrm{He}$ to $^{208}\mathrm{Pb}$ and incident neutron momenta in the range 3 GeV/$c$--300 GeV/$c$ are considered; the commonly used approach which approximates the square of the nuclear wave function by a product of one-body densities is carefully analyzed, showing that $\mathit{NN}$ correlations can play a non-negligible role in high energy scattering off nuclei
