What is the difference between instantons and sphalerons? If they are different, how do they violate baryon and lepton number in the standard electroweak theory?
What is the effect on leptogenesis in the standard model if the electroweak phase transition is (i) first order and (ii) second order?
SM provides baryogenesis via leptogenesis due to anomalies and sphaleron processes. I have a few questions on it. How exactly the anomalies in lepton and baryon currents provide convertation of ...
As I understand it, if you try to "pull apart" a hadron with sufficient force, you just make more hadrons. Would the same thing happen in a Big Rip? (this answer suggests it would, as long as the ...
