Propagators approximated by meromorphic functions with complex conjugated poles are widely used to model the infrared behavior of QCD Green’s functions. In this paper, analytical solutions for two point correlators made out of functions with comple

We study non-perturbatively the time evolution of cascade decay for generic fields $\pi \to {{\phi }_{1}}{{\phi }_{2}}\to {{\phi }_{2}}{{\chi }_{1}}{{\chi }_{2}}$ and obtain the time dependence of amplitudes and populations for the resonant and final

In many domains of physics, methods are needed to deal with non-perturbative aspects. I want here to argue that a good approach is to work on the Borel transforms of the quantities of interest, the singularities of which give non-perturbative contrib

We device an efficient book-keeping of excluded energy-sign and scattering-channel combinations for the loop four-momenta associated with massive quasi-particles, circulating in (connected) bubble diagrams subject to vertex constraints inherited from

We summarize our recent work [1-3] concerning the formulation of two-particle-irreducible (2PI) functional techniques for abelian gauge field theories.

We study a $\phi^4$-theory at finite temperature in a finite volume. Quantum, thermal and volume fluctuations are treated with the functional renormalisation group. Specifically, we focus on the interplay of temperature and length scales driving the
