Resumen:
We derive an exact formula for the cusp anomalous dimension at small angles.This is done by relating the latter to the computation of certain 1/8 BPS Wilson loopswhich was performed by supersymmetric localization. This function of the coupling alsodetermines the power emitted by a moving quark in N = 4 super Yang Mills, as well as thecoecient of the two point function of the displacement operator on the Wilson loop. Bya similar method we compute the near BPS expansion of the generalized cusp anomalousdimension
