Resummation in QFT with Meijer G-functions
Oleg Antipin, Alessio Maiezza, Juan Carlos Vasquez
We employ a recent resummation method to deal with divergent series, based on the Meijer G-function, which gives access to the non-perturbative regime of any QFT from the first few…
Multifield Polygonal Bounces
Victor Guada, Alessio Maiezza, Miha Nemevšek
We propose a new approach for computing tunneling rates in quantum or thermal field theory with multiple scalar fields. It is based on exact analytical solutions of piecewise linea…
Resummation and renormalons in a general Quantum Field Theory
Alessio Maiezza, Juan Carlos Vasquez
We generalize the concept of Borel resummability and renormalons to a quantum field theory with an arbitrary number of fields and couplings, starting from the known notion based on…
