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.

Light Dark Matter, Naturalness, and the Radiative Origin of the Electroweak Scale

TL;DR: In this paper, the authors study classically scale invariant models in which the Standard Model Higgs mass term is replaced in the Lagrangian by a Higgs portal coupling to a complex scalar field of a dark sector.

Dark Matter in Classically Scale-Invariant Two Singlets Standard Model

TL;DR: In this article, the authors consider a model where two new scalars are introduced in the standard model, assuming classical scale invariance, and the impact of these scalars on the Higgs potential is discussed.

On the perturbative expansion at high temperature and implications for cosmological phase transitions

TL;DR: In this article, the authors revisited the perturbative expansion at high temperature and investigated its convergence by inspecting the renormalisation scale dependence of the effective potential, showing that at zero temperature, the improved effective potential is scale independent at one-loop, due to the misalignment of loop and coupling expansions.

On the gauge dependence of the Standard Model vacuum instability scale

Abstract: After reviewing the calculation of the Standard Model one-loop effective potential in a class of linear gauges, we discuss the physical observables entering the vacuum stability analysis. While the electroweak-vacuum-stability bound on the Higgs boson mass can be formally proven to be gauge independent, the field value at which the effective potential turns negative (the so-called instability scale) is a gauge dependent quantity. By varying the gauge-fixing scheme and the gauge-fixing parameters in their perturbative domain, we find an irreducible theoretical uncertainty of at least two orders of magnitude on the scale at which the Standard Model vacuum becomes unstable.

Renormalization-group improved inflationary scalar electrodynamics and SU(5) scenarios confronted with Planck 2013 and BICEP2 results

TL;DR: In this article, the authors investigated the possibility to construct inflationary models for the renormalization-group improved potentials corresponding to scalar electrodynamics and to $SU(2)$ and$SU(5)$ models.

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).

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.
