-
At some point an unknown reaction called baryogenesis violated the conservation of baryon number, leading to a very small excess of quarks and leptons over antiquarks and anti-leptons—of the order of 1 part in 30 million.

At the Buzz Aldrin Advanced Research Laboratory on the moon, Doctor Julia Hess adjusted the baryogenesis detector for the hundredth time.

In particular, I focus on candidates for dark matter, and their possible origin in beyond the standard model physics at the TeV scale, on models of baryogenesis, and on the logical possibilities for the origin of cosmic acceleration - the cosmological constant, dynamical dark energy and modified gravity.

But if the baryons in the universe were to be annihilated by the inverse of baryogenesis, again via electroweak quantum tunneling which is allowed in the Standard Model, as baryon number minus lepton number B - L is conserved, then this would force the Higgs field toward its absolute vacuum, cancelling the positive cosmological constant and thereby forcing the universe to collapse.

As required by the Standard Model, the net baryon number was created in the early universe by baryogenesis via electroweak quantum tunneling.

I need to read the Riotto-Trodden paper to get more of the details and how this plays out in baryogenesis.
-
For those of you who care about the numbers, according to relatively current calculations, baryogenesis is possible if the lightest Higgs particle has a mass less than 120 GeV, and the lightest stop has a mass less than the top quark mass.
-
The generation of the BAU through one of these mechanisms is what is known as baryogenesis.
-
Since the equilibrium description of particle phenomena is extremely accurate at electroweak temperatures, baryogenesis cannot typically occur at such low scales without the aid of phase transitions.
