Electroweak Higgs Potentials and Vacuum Stability

Marc Sher
- 01 Aug 1989 - 
- Vol. 179, pp 273-418
TLDR
In this article, the method of calculating radiative corrections to the scalar potentials is reviewed, with an emphasis on renormalization group improvement of the potential, and the results are then applied to the standard model to derive stringent bounds on Higgs and fermion passes.

Bounds on scalar masses in two Higgs doublet models

TL;DR: In this article, a thorough analysis of stability and perturbativity bounds in several versions of the two-Higgs doublet model was performed, for both CP-conserving and spontaneously broken CP minima.

Non-Minimal B-L Inflation with Observable Gravity Waves

TL;DR: In this article, the authors considered non-minimal λ ϕ 4 inflation in a gauged non-supersymmetric B − L model containing the gravitational coupling ξ R Φ † Φ, where R denotes the Ricci scalar and the standard model singlet inflaton field Φ spontaneously breaks the U ( 1 ) B − l symmetry.

The effective potential and the differential equations method for Feynman integrals

TL;DR: In this paper, the authors apply the differential equations method to the calculation of the effective potential in O(N) scalar O4 theory and discuss the result vis a vis the renormalisation group equation.

Electroweak vacuum stability and diphoton excess at 750 GeV

TL;DR: In this article, the authors interpret the diphoton excess as the on-shell production of a real singlet scalar in the pp -> S -> gamma gamma channel and introduce a vector-like fermion F which carries both color and electric charges.

Two-Higgs-doublet models and enhanced rates for a 125 GeV Higgs

TL;DR: In this article, the authors examined the level of enhancement that can be achieved in the ZZ and γγ channels for a two-Higgs-doublet model Higgs boson (either the light h or the heavy H) with mass near 125 GeV after imposing all constraints from LEP data, B physics, precision electroweak data, vacuum stability, unitarity and perturbativity.

Inflationary universe: A possible solution to the horizon and flatness problems

TL;DR: In this paper, the authors proposed a model of hot big-bang cosmology where the early universe is assumed to be highly homogeneous, in spite of the fact that separated regions were causally disconnected (horizon problem).

Quantum Field Theory

TL;DR: In this article, a modern pedagogic introduction to the ideas and techniques of quantum field theory is presented, with a brief overview of particle physics and a survey of relativistic wave equations and Lagrangian methods.

CP Conservation in the Presence of Pseudoparticles

TL;DR: In this paper, the authors give an explanation of the conservation of strong interactions which includes the effects of pseudoparticles, and they find it is a natural result for any theory where at least one flavor of fermion acquires its mass through a Yukawa coupling to a scalar field which has nonvanishing vacuum expectation value.

CP Violation in the Renormalizable Theory of Weak Interaction

TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.

A new inflationary universe scenario: A possible solution of the horizon, flatness, homogeneity, isotropy and primordial monopole problems

TL;DR: A new inflationary universe scenario is suggested in this paper, which is free of the shortcomings of the previous one and provides a possible solution of the horizon, flatness, homogeneity and isotropy problems in cosmology.
