Impact of Gravity on Vacuum Stability
Vincenzo Branchina, Emanuele Messina, Dario Zappala
In a pioneering paper on the role of gravity on false vacuum decay, Coleman and De Luccia showed that a strong gravitational field can stabilize the false vacuum, suppressing the f…
Stability and UV completion of the Standard Model
Vincenzo Branchina, Emanuele Messina
The knowledge of the stability condition of the electroweak (EW) vacuum is of the greatest importance for our understanding of beyond Standard Model (BSM) physics. It is widely bel…
PT-symmetric theory in d=0 dimensions
Carl M. Bender, Vincenzo Branchina, Emanuele Messina
A detailed study of a PT-symmetric zero-dimensional quartic theory is presented and a comparison between the properties of this theory and those of a conventional quartic theory is…
The lifetime of the electroweak vacuum and sensitivity to Planck scale physics
Vincenzo Branchina, Emanuele Messina, Marc Sher
If the Standard Model (SM) is valid up to extremely high energy scales, then the Higgs potential becomes unstable at approximately GeV. However, calculations of the lifet…
Top mass determination, Higgs inflation, and vacuum stability
Vincenzo Branchina, Emanuele Messina, Alessia Platania
The possibility that new physics beyond the Standard Model (SM) appears only at the Planck scale is often considered. However, it is usually argued that new physics interacti…
Stability, Higgs Boson Mass and New Physics
Vincenzo Branchina, Emanuele Messina
When the particle with mass GeV discovered at LHC is identified with the Higgs boson of the Standard Model, intriguing and challenging questions arise. Among them, the i…
