The next QFT colloquium, titled “Multi-particle observables from a finite Euclidean spacetime”, awaits us this Friday. In my talk, I will focus on one aspect of the colloquium and present the method to compute and extract spectral densities from lattice simulations (see arXiv:2111.12774). The crucial step is to bypass the direct computation of a Laplace transform (which cannot be done numerically) by using so called smearing kernels.
