Original study of the theory. Analysis of all orders in and resummations
Vincenzo Branchina, Alberto Chiavetta, Filippo Contino
In a recent work the Green's functions of the -symmetric scalar theory were calculated at the first order of the logarithmic expansion, i.e. at first…
Non-linear and weak-coupling expansion in Quantum Field Theory
Vincenzo Branchina, Alberto Chiavetta, Filippo Contino
A formal expansion for the Green's functions of an interacting quantum field theory in a parameter that somehow encodes its "distance" from the corresponding non-interacting one wa…
Direct Higgs-gravity interaction and stability of our Universe
Vincenzo Branchina, Eloisa Bentivegna, Filippo Contino +1
The Higgs effective potential becomes unstable at approximately GeV, and if only standard model interactions are considered, the lifetime of the electroweak vacuum tu…
Electroweak vacuum lifetime in two Higgs doublet models
V. Branchina, F. Contino, P. M. Ferreira
We study the stability of neutral electroweak vacua in two Higgs doublet models, and calculate the lifetime of these states when the parameters are such that they are false vacua.…
Protecting the Stability of the EW Vacuum from Planck-Scale Gravitational Effects
Vincenzo Branchina, Filippo Contino, Apostolos Pilaftsis
We investigate the stability of the Standard-Model Electroweak (EW) vacuum in the presence of Planck-scale suppressed operators of the type that involve t…
