CMB-S4: Forecasting Constraints on Primordial Gravitational Waves
TL;DR: In this article , a power-spectrum-based semi-analytic projection tool is proposed to forecast the tensor-to-scalar ratio in the presence of Galactic foregrounds and gravitational lensing of the CMB.

TL;DR: The Cosmology Large Angular Scale Surveyor (CLASS) as mentioned in this paper is a four telescope array designed to characterize primordial gravitational waves from inflation and the optical depth to reionization through a measurement of the polarized cosmic microwave background (CMB) on the largest angular scales.

On the constant-roll inflation
Zhu Yi,Yungui Gong +1 more
TL;DR: In this article, the primordial power spectra of scalar and tensor perturbations during slow-roll inflation were calculated with the method of Bessel function approximation, and the numerical results were compared with the analytical results derived from the Bessel functions.

Universes inside a Λ black hole
TL;DR: In this paper, a spherically symmetric globally regular solution to the Einstein equations with variable cosmological term Λ μν, asymptotically Λg μν as r → 0 with Λ of the scale of symmetry restoration is presented.

Consistently violating the non-Gaussian consistency relation
Sander Mooij,Gonzalo A. Palma +1 more
TL;DR: In this article, it was shown that the bispectrum's squeezed limit of non-attractor models of inflation continues to respect a relation dictated by the evolution of the background.

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).
Journal ArticleDOI
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.
