Geometric Baryogenesis from Shift Symmetry | | Andrea De Simone

14 Dec 2016 | | Abstract: | 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. | | Source: | arXiv, 1612.4824 | | Services: | Forum | Review | PDF | Favorites | |
