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.

Theoretical models for Dark Matter: from WIMPs to Primordial Black Holes

Davide Racco
TL;DR: In this paper, effective field theories have been used consistently for the recast of collider searches in the presence of gauge anomalies, and a model for the generation of Primordial Black Holes relying on the metastability of the Higgs vacuum was proposed.

Right-handed Neutrino Dark Matter, Neutrino Masses, and non-Standard Cosmology in a 2HDM

TL;DR: In this article, the authors explore the dark matter phenomenology of a weak-scale right-handed neutrino in the context of a Two Higgs Doublet Model and outline the region of parameter space that obeys collider, perturbative unitarity and direct detection constraints.
Journal ArticleDOI

Two-Higgs-doublet type-II and -III models and $t\rightarrow c h$ at the LHC

TL;DR: In this paper, the authors study the constraints of the generic two-Higgs-doublet model (2HDM) type-III and the impacts of the new Yukawa couplings.

On the origin of approximate custodial symmetry in the two-higgs doublet model

TL;DR: In this article, the authors show that the consistent implementation of the multiple point principle (MPP) in the general nonsupersymmetric two-Higgs doublet model (2HDM) can lead to a set of approximate global custodial symmetries that ensure CP conservation in the Higgs sector and the absence of flavor changing neutral currents in the considered model.

Gravitational corrections to Higgs potentials

TL;DR: In this article, the Higgs potential at large field values corresponding to scales in the range above $10−10−1 GeV was derived in away which is independent of the choice of conformal frame for the spacetime metric.

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.
