Query: Nonperturbative enhancement of superloop at strong coupling   We address the near-collinear expansion of NMHV six-particle scattering
amplitudes at strong value of 't Hooft coupling in planar maximally
supersymmetric Yang-Mills theory. We complement recent studies of this
observable within the context of the Pentagon Operator Product Expansion, via
the dual superWilson loop description, by studying effects of multiple scalar
exchanges that accompany (or not) massive flux-tube excitations. Due to the
fact that holes have a very small, nonperturbatively generated mass which is
exponentially suppressed in 't Hooft coupling, their exchanges must be resummed
in the ultraviolet limit. This procedure yields a contribution to the
expectation value of the superloop which enters on equal footing with the
classical area, --- a phenomenon which was earlier observed for MHV amplitudes.
In all components, the near-massless scalar exchanges factorize from the ones
of massive particles, at leading order in strong coupling.
