We study the real time correlators of scalar glueball operators forYang-Mills theory at finite temperature in flat space. The analytic structureof the frequency space propagator in perturbative field theory is seen to bequalitatively different to the strong coupling results that may be obtainedfrom perturbations about AdS black hole spacetimes: we find branch cuts ratherthan poles. This difference appears to persist away from the strict zero andinfinite coupling limits, possibly suggesting a phase transition in large Nthermal N = 4 SYM theory as a function of the 't Hooft coupling.
