In DIS the Bjorken limit is given by the conditions: $Q^2 \rightarrow \infty$, $\nu \rightarrow \infty$ and $x=Q^2/(2M\nu)$ is finite, where $Q^2$ is the opposite of the transferred momentum, $M$ is the proton mass and $\nu$ is the transferred energy. In this limit, the structure functions of the nucleons are functions of $x$ only and don't depend on $Q^2$.
The deep inelastic limit instead is the condition in which the invariant mass $W$ of the hadronic system that is produced in the electron-nucleon interaction is much bigger than the proton mass $M$. Please correct me if I'm wrong.
But, are the Bjorken limit and the deep inelastic limit the same condition?
