Exact results for static and radiative fields of a quark in N=4 super
Yang-Mills    [PDF]

Bartomeu Fiol, Blai Garolera, Aitor Lewkowycz

In this work (which supersedes our previous preprint arXiv:1112.2345) we
determine the expectation value of the N=4 SU(N) SYM Lagrangian density
operator in the presence of an infinitely heavy static particle in the
symmetric representation of SU(N), by means of a D3-brane probe computation.
The result that we obtain coincides with two previous computations. We argue
that these agreements go beyond the D-brane probe approximation, which leads us
to propose an exact formula for various quantities, among them the total energy
loss by radiation of a heavy particle in the fundamental representation.
