Gauge-invariant Higgs boson mass bounds from the physical effective potential

  title={Gauge-invariant Higgs boson mass bounds from the physical effective potential},
  author={Daniel Boyanovsky and W. A. Loinaz and R. S. Willey},
  journal={Physical Review D},
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
Beyond the Standard Model: Scalar dark matter, and, lepton flavor violation
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
Precision Tunneling Rate Calculations in Quantum Field Theory and the Ultimate Fate of Our Universe
One of the most concrete implications of the discovery of the Higgs boson is that, in the absence of physics beyond the Standard Model, the long-term fate of our universe can now be establishedExpand
Higgs potential near-criticality from a de Sitter swampland-like condition
Motivated by the recently proposed de Sitter swampland conjecture, a formally same condition imposed instead on the convex and real exact effective potential is contemplated. Compared to the originalExpand

Gauge dependence of lower bounds on the Higgs boson mass derived from electroweak vacuum stability constraints
We examine the gauge dependence of lower bounds on the Higgs boson mass obtained from the requirement that the electroweak vacuum be the global minimum of the effective potential. We study a simpleExpand
Constraints on the Higgs boson properties from the effective potential
We review the constraints on Higgs boson properties from effective potential methods. In the Standard Model, the requirement of stability (or metastability) of the standard electroweak minimum putsExpand
Electroweak Baryogenesis and Higgs Physics
Electroweak Baryogenesis is a particularly attractive theoretical scenario, since it relies on physics which can be tested at present high energy collider facilities. Within the Standard Model, itExpand
