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.

Theory and phenomenology of two-Higgs-doublet models

TL;DR: In this article, theoretical and phenomenological aspects of two-Higgs-doublet extensions of the Standard Model are discussed and a careful study of spontaneous CP violation is presented, including an analysis of the conditions which have to be satisfied in order for a vacuum to violate CP.

Higgs mass and vacuum stability in the Standard Model at NNLO

TL;DR: In this article, the authors presented the first complete next-to-next-toleading order analysis of the Standard Model Higgs potential, showing that at the Planck scale, absolute stability of the potential is not guaranteed at 98% C.L. for Mh < 126 GeV.

The anatomy of electroweak symmetry breaking: Tome I: The Higgs boson in the Standard Model

TL;DR: In this paper, the authors focused on the mechanism of electroweak symmetry breaking and the fundamental properties of the Higgs particle of the Standard Model and its decay modes and production mechanisms at hadron colliders and at future lepton colliders.

Investigating the near-criticality of the Higgs boson

TL;DR: In this article, the parameters of the Higgs potential, the top Yukawa coupling and the electroweak gauge couplings were extracted from data with full 2-loop NNLO precision.

A “renormalisation group improved” study of the gauge hierachy problem

TL;DR: In this paper, a toy model was used to study higher order contributions to the effective potential which contain terms of the type (λ log υ 1 2 υ 2 2 2 ) n where λ is some Higgs coupling and υ is the vacuum expectation values of certain scalar fields whose ratio we require phenomenologically to be extremely large ( υ − 1 2 ε 2 ≈ 10 24 or so) and they can be absorbed into a suitably defined coupling constant whose evolution equations seem to indicate that no natural large hierachy is possible.

Reply to "Comment on 'Calculating the weak scale in supergravity models' "

TL;DR: Comment Drees discusses the issues of whether my method sums the leading logs, the use or abuse of the infrared scale ${Q}_{0}$, a possible ambiguity in my definition of the renormalized scalar masses, and the threshold effects at the ultraviolet scale.

Calculating the weak scale in supergravity models.

TL;DR: A renormalization framework is presented for calculating radiative SU(2) x U(1) gauge symmetry breaking in no-scale supergravity models and a coupled set of linear algebraic equations is obtained, whose solutions coincide with those of the RG approach to the order of accuracy of the latter method.

Vacuum stability bounds on enhanced couplings of light Higgs fields

TL;DR: In the standard model with more than one Higgs doublet, Yukawa couplings can be enhanced by ratios of vacuum values as mentioned in this paper, and the sensitivity of the result to higher order corrections and to effects of the additional scalars, and the validity of the effective field theory approximation.

Upper bounds on the higgs mass

TL;DR: Using radiative corrections as the origin of spontaneous symmetry breaking (SSB), charged and neutral Higgs boson masses can be derived easily as mentioned in this paper, and experimental constraints allow us to estimate mH0 ≲349 GeV and mH± ≲125 GeV for mt ⩽ 80 GeV.
