Axion Induced Baryogenesis and Baryon Asymmetry Proposed

by Tommy on 20/12/2016

Here is one that is dear to my heart. It’s a start, I guess.

At least some of this is not being taken seriously, though.

Geometric Baryogenesis from Shift Symmetry, Andrea De Simone, Takeshi Kobayashi and Stefano Liberati, SISSA 64/2016/FISI (14 December 2016)

We present a new scenario for generating the baryon asymmetry of the universe that is induced by a Nambu-Goldstone (NG) boson. The shift symmetry naturally controls the operators in the theory, while allowing the NG boson to couple to the spacetime geometry. The cosmological background thus sources a coherent motion of the NG boson, which leads to baryogenesis. Good candidates of the baryon-generating NG boson are the QCD axion and axion-like fields. In these cases the axion induces baryogenesis in the early universe, and can also serve as dark matter in the late universe.

Some very prestigious popular science journalists assured me that the axion doesn’t exist.

Some crackpots and cranks agreed, and so that’s the end of that.
