We study a simplified version of the standard electroweak model and introduce the concept of the physical gauge-invariant effective potential in terms of matrix elements of the Hamiltonian in physical states. This procedure allows an unambiguous identification of the symmetry breaking order parameter and the resulting effective potential as the energy in a constrained state. We explicitly compute the physical effective potential at one loop order and improve it using the renormalization group… Expand

Gauge-Independent Scales Related to the Standard Model Vacuum Instability
The measured (central) values of the Higgs and top quark masses indicate that the standard model (SM) effective potential develops an instability at high field values. The scale of this instability,Expand
Interplay of infrared divergences and gauge dependence of the effective potential
The perturbative effective potential suffers infrared (IR) divergences in gauges with massless Goldstones in their minima (like the Landau or Fermi gauges), but the problem can be fixed by a suitableExpand
Effective operators and vacuum instability as heralds of new physics
For a light enough Higgs boson, the effective potential of the Standard Model develops a dangerous instability at some high energy scale, ?, signalling the need for new physics below that scale. OnExpand
Complex scalar singlet dark matter: Vacuum stability and phenomenology
We analyze one-loop vacuum stability, perturbativity, and phenomenological constraints on a complex singlet extension of the standard model scalar sector containing a scalar dark matter candidate. WeExpand
Standard Model with gauge inert variables
The Standard Model of electroweak interactions has been recast as a gauge free theory where the fields present in the Lagrangian are made inert under $SU(2)_L \times U(1)_Y$ gauge transformations.Expand

The Standard Model of particle physics is a highly successful theory of fundamental particle interactions, especially in light of the recent discovery of a Higgs-like boson at the LHC. Nonetheless,Expand
