UHE neutrinos: higher twists, scales, saturation

arXiv:1011.2611 · doi:10.1063/1.3601381

Abstract

It is shown that in the ultra-high energy neutrino interactions the higher twist corrections brought about by the non-conservation of the top-bottom current dramatically change the longitudinal structure function, $F_{L}$ . To the Double Leading Log Approximation simple and numerically accurate formulas for $F_{L}$ and $I ¨ ^{I^½ N}$ are derived.
