Physical Tuning and Naturalness
C. Branchina, V. Branchina, F. Contino
We present a radically new proposal for the solution of the naturalness/hierarchy problem, where the fine-tuning of the Higgs mass finds its physical explanation and the well-known…
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…
