Abstract :

We study the vacuum expectation value of a generalized class of bosonic
and fermionic BPS Wilson loops in ABJM theory. Exploiting the relation
between BPS Wilson loops, cusp anomalous dimension and Bremsstrahlung
function we conjecture an exact expression for the latter in the 1/2-BPS
case. Using results from localization, we show that in the weak-coupling
limit our proposal agrees with the perturbative result, while at strong
coupling it matches the leading term of the string prediction.
