DESCRIPTION:Speakers: Alessandro Lupo (cern)\n\nIn this talk we discuss te
 chnical aspects of the problem of computing Minkowskian correlators\, from
  which we can access scattering amplitudes and decay rates\, starting from
  Euclidean correlators\, which we compute in lattice simulations. The brid
 ge is provided by the spectral function of the Källén–Lehmann represen
 tation\, and we discuss how to compute this quantity on the lattice. The p
 roblem is delicate and we focus this talk on how to deal with its systemat
 ic error\, whether we can estimate it reliably\, or whether we can avoid i
 t completely using bounding inequalities.\n\nhttps://indico.cern.ch/event/
