Abstract
We review the current status of calculations
of the HQET field anomalous dimension and the cusp anomalous dimension.
In particular, we give the results at 4 loops for the quartic Casimir contribution,
and for the full QED case, up to $\varphi^6$ in the small angle expansion.
Furthermore, we discuss the leading terms in the anti-parallel lines limit at four loops.
