Axion monodromy inflation with sinusoidal corrections

Tatsuo Kobayashi, Osamu Seto and Yuya Yamaguchi.

in Progress of Theoretical and Experimental Physics

P ublished online October 2014 .

Journal Article. Subjects: Cosmology. 2970 words.

We study the axion monodromy inflation with a non-perturbatively generated sinusoidal term. The potential form is a mixture between the natural inflation and the axion monodromy inflation...

Baryon Asymmetry of the Universe and Neutrinos

Mikhail Shaposhnikov.

in Progress of Theoretical Physics

July 2009; p ublished online July 2009 .

Journal Article. Subjects: Cosmology; Particles and Fields. 0 words.

Our Universe is charge-asymmetric: it contains no antimatter in amounts comparable to matter. This fact provides cosmological evidence for the nonconservation of baryon number as well as...
