DESCRIPTION:In the context of Quantum Chromodynamics\, non-perturbative ob
 servables such as the low-lying spectrum of hadrons can be extracted from 
 the theory discretized on a Euclidean space-time lattice and simulated on 
 a computer. Real-time quantities on the other hand\, such as phase shifts\
 , resonance widths\, or transport properties at finite temperature\, canno
 t be straightforwardly computed. In some cases however real-time effects l
 eave signatures in the Euclidean theory which can be isolated in certain k
 inematical regimes. I describe several examples of this type at zero and f
 inite-temperature.
