Neutrino Charged Current (ν CC) interaction cross-section on nucleon as a function of neutrino energy. Data at sub-TeV energies are ν_μ CC from [37]. Data and band at the highest energies are from the IceCube experiment, [38, 39], averaged over ν_μ and ${\overline{\nu }}_{\mu }$. Lines are simulations from FLUKA: black ν_μ, red 0.5(${\nu }_{\mu }+{\overline{\nu }}_{\mu })$. On the right, σ/E_ν. Bottom, zoomed view of the high-energy part, σ not divided by ν energy.
