The paper proposes inverse electroweak baryogenesis where baryon asymmetry arises from equilibrium sphaleron processes in the presence of a conserved global charge during an inverse phase transition that alters electroweak symmetry breaking strength.

abstract
We consider the effects of particle transport in the topological defect-mediated electroweak baryogenesis scenarios of Ref. 1. We analyze the cases of both thin and thick defects and demonstrate an enhancement of the original mechanism in both cases due to an increased effective volume in which baryogenesis occurs. This phenomenon is a result of imperfect cancellation between the baryons and antibaryons produced on opposite faces of the defect.

An axion-like particle's domain wall or shock wave induces an electroweak phase boundary whose motion creates a local B+L chemical potential that biases active sphalerons to generate net baryon asymmetry.
Electroweak-symmetric domain walls produce the observed baryon asymmetry via CP-violating semiclassical forces, transport, sphalerons, and interference between the two wall faces in a singlet-extended Standard Model.
