Description

For Deep Inelastic neutrino-proton scattering in the combination $\nu P - \bar{\nu} P$, we compute the exact $\mathcal{O}(\alpha_s^3)$ perturbative QCD corrections to the charged-current structure functions $F_2$, $F_L$ and $F_3$. These results supersede previous approximations based on the first few Mellin moments by providing all-$N$ expressions for the coefficient functions. We discuss the numerical size of the third-order corrections and their behaviour in the threshold and high-energy limits.
