Abstract:
We propose a mechanism called axiogenesis where the cosmological excess of baryons over antibaryons is generated from the rotation of the QCD axion.
The Peccei-Quinn (PQ) symmetry may be explicitly broken in the early universe, inducing the rotation of a PQ charged scalar field.
The rotation corresponds to the asymmetry of the PQ charge, which is converted into the baryon asymmetry via QCD and electroweak sphaleron transitions.
In the concrete model we explore, interesting phenomenology arises due to the prediction of a small decay constant and the connections with new physics at the LHC and future colliders and with Axion dark matter.

In contrast however: Quantum FFF Theory says:
The big bang was the explosion of a former big Crunch Rigid Elastic Transformer String based black hole nucleus.
Transformer strings are supposed to be so called "primal substance"able to change into electron or positrons (all Leptons) or Photon Gluons, which are all the accessories of compound Quarks and Bosons.
As extra variant it can transform into an anti Graviton ( with a pressure effect in equilibrium with the pressure of the Casimir Axion-Higgs field)
This Big Bang nucleus is assumed to be compacted and compressed by the oscillating Axion-Higgs vacuum chiral lattice, which was decreasing in strength by the vacuum lattice absorption of the Big Crunch black hole itself !.
At the moment that the decreasing Axion-Higgs vacuum pressure on the Big Crunch nucleus becomes equalized with the internal elastic bounce of all compressed strings, the BIG BANG nucleus start spitting out chunks of Black Hole nuclei and an equal set of newly shaped but left or right handed oscillating Axion-Higgs lattices forming each a new Universal bubble in what I call the Raspberry Multiverse.
Rigid String nuclei ( string knots) could be stable compressed by the local vacuum lattice, I call them Dark Matter Black Holes.!
