Query: The Bremsstrahlung function of $\mathcal{N} \!= \!2 $ SCQCD   For $SU(N)$ superconformal QCD we perform a three-loop calculation of the
generalized cusp anomalous dimension of the BPS Wilson loop operator using HQET
formalism. We obtain an expression which is valid at generic geometric and
internal angles and finite gauge group rank $N$. For equal and opposite angles
this expression vanishes, proving that at these points the cusp becomes BPS.
From its small angle expansion we derive the corresponding Bremsstrahlung
function at three loops, matching the matrix model prediction given in terms of
derivatives of the Wilson loop on the ellipsoid. Finally, we discuss possible
scenarios at higher loops, with respect to the existence of a universal
effective coupling in an integrable subsector of the model.
