The Intrinsic Bispectrum of the Cosmic Microwave Background
TL;DR: In this paper, SONG is used to estimate the intrinsic CMB non-Gaussianity arising from the non-linear evolution of density perturbations in the early universe.

Cosmic Strings and Their Induced Non-Gaussianities in the Cosmic Microwave Background
TL;DR: In this article, the signatures of Nambu-Goto cosmic strings would induce in various observables ranging from the one-point function of the temperature anisotropies to the bispectrum and trispectrum.

Polynomial Chaotic Inflation in Supergravity
Kazunori Nakayama,Kazunori Nakayama,Fuminobu Takahashi,Fuminobu Takahashi,Tsutomu T. Yanagida +4 more
TL;DR: In this paper, a general polynomial chaotic inflation model for supergravity was presented, for which the predicted spectral index and tensor-to-scalar ratio lie within the 1 sigma region allowed by the Planck results.

Constraining scalar fields with stellar kinematics and collisional dark matter
TL;DR: In this paper, an upper limit for the boson star compactness was derived by exploiting the stellar dynamics at the centre of the galaxy and assuming that these dynamics can be explained by a single boson.

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.

Unity of All Elementary Particle Forces
Howard Georgi,Sheldon L. Glashow +1 more
TL;DR: In this paper, strong, electromagnetic, and weak forces are conjectured to arise from a single fundamental interaction based on the gauge group SU(5), which is known as SU(4).

Decay of the false vacuum at finite temperature
TL;DR: In this article, a general theory of the decay of the metastable phase (false vacuum) at a finite temperature is developed, which will make it possible to study kinetics of phase transitions in a wide class of theories without complicated computer calculations.
Journal ArticleDOI
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.
