Vacuum instability, cosmology and constraints on particle masses in the Weinberg-Salam model
TLDR
In this paper, a set of constraints on the masses of particles in the Weinberg-Salam model is obtained and it is shown that in the absence of superheavy fermions (m F ≲ 100 GeV) the Higgs meson mass should exceed the Coleman-Weinberg value ≈9.2 GeV for sin 2 φW ≈ 0.23.About:

Electroweak Higgs Potentials and Vacuum Stability
TL;DR: 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.
Journal ArticleDOI
The inflationary Universe
TL;DR: According to the inflationary universe scenario, the Universe in the very early stages of its evolution was exponentially expanding in the unstable vacuum-like state as mentioned in this paper, and at the end of the exponential expansions (inflation) the energy of a classical scalar field transforms into the energy energy of hot dense matter, and the subsequent evolution of the Universe is described by the usual hot universe theory.

Fate of the false vacuum at finite temperature: Theory and applications
TL;DR: The theory of first-order phase transitions in spontaneously broken gauge theories is investigated in this paper, and some implications of this theory for cosmology and for elementary particle physics are discussed.

Supergravity Domain Walls
Mirjam Cvetič,Harald H. Soleng +1 more
TL;DR: In this paper, the authors review the status of domain walls in N = 1 supergravity theories for the vacuum domain walls as well as dilatonic domain walls and provide a systematic analysis of the space-time in these domain wall backgrounds and the special role that supersymmetry is playing in determining the nature of such configurations.

Phase transitions in gauge theories and cosmology
TL;DR: In this article, it is shown that at a sufficiently large temperature a phase transition takes place after which almost all elementary particles in the hot super-dense matter become massless and weak interactions become long-range like electromagnetic interactions.

TL;DR: In this paper, the Weinberg model is applied to a large system of thermodynamically equilibrium weakly interacting particles and it is shown that at a temperature higher than about 10 3 GeV the symmetry broken at lower temperature is re-established, the masses of the intermediate bosons vanish and weak interaction becomes a long-range one.

Mass of the Higgs Boson
TL;DR: The stability of the Higgs-boson mass has been shown to give a lower bound of 3.72 GeV for the SU(2) \ensuremath{\bigotimes} U(1) model as mentioned in this paper.
