Off-diagonal distributions fixed by diagonal partons at small $x$ and $ξ$

Authors

Description

We show that the off-diagonal (or skewed) parton distributions are completely determined at small $x$ and $ξ$ by the (conventional) diagonal partons. We present predictions which can be used to estimate the off-diagonal distributions at small $x$ and $ξ$ at any scale.
