Dynamics of quintessential inflation
Zhai Xiang-Hua,Zhao Yi-Bin +1 more
TL;DR: In this article, a realistic model of quintessential inflation with radiation and matter is proposed. But the model is not suitable for the current astronomical observation. And the authors show that the modular part of the complex field plays the role of the inflaton whereas the argument part is the quintessence field.

O(N) Quintessence with a Cosine-Type Potential
TL;DR: In this article, a cosine-type quintessence model with O(N) internal symmetry was proposed, in which the scalar field Φa possesses an O(n)-internal symmetry.

CP Conservation in the Presence of Pseudoparticles
R.D. Peccei,Helen R. Quinn +1 more
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.

A new light boson
TL;DR: In this article, it was pointed out that a global U(1) symmetry, introduced in order to preserve the parity and time-reversal invariance of strong interactions despite the effects of instantons, would lead to a neutral pseudoscalar boson, the "axion", with mass roughly of order 100 keV to 1 MeV.

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).

Cosmology of the invisible axion
TL;DR: In this article, the authors identify a new cosmological problem for models which solve the strong CP puzzle with an invisible axion, unrelated to the domain wall problem, and identify the energy density stored in the oscillations of the classical axion field does not dissipate rapidly; it exceeds the critical density needed to close the universe unless fa ⩽ 1012GeV wherefa is the axion decay constant.

Anomaly cancellations in supersymmetric D=10 gauge theory and superstring theory
TL;DR: In this article, a superstring theory for E 8 × 8 × E 8 has been constructed, based on SO(32) and the remaining pieces of all the anomalies cancel if the gauge group is SO (32) or E 8×E 8.
