Thus, the AD mechanism may explain the asymmetry between matter and antimatter in the current Universe.
It was proposed in 1985 by Ian Affleck and Michael Dine of Princeton University.
As the latter decay into fermions during the early Universe, the net baryon number that they carry can then form the currently observed excess of ordinary baryons.
This occurs due to interactions of the scalars with the inflaton field, resulting in CP violations.
[2][3] The AD mechanism must have occurred during or after the reheating event that followed cosmic inflation.
