CP conservation in the strong interactions
Wen-Yuan Ai, Bjorn Garbrecht, Carlos Tamarit
We discuss matters related to the point that topological quantization in the strong interaction is a consequence of an infinite spacetime volume. Because of the ensuing order of li…
Baryogenesis and EDMs in the 2HDM+CS
Björn Garbrecht, Edward Wang
We perform the first joint analysis of baryogenesis from initial Higgs charges (also called Higgsogenesis) and EDMs in a model with two Higgs doublets, a complex scalar and a Major…
Instantons meet resonances: Unifying two seemingly distinct approaches to quantum tunneling
Björn Garbrecht, Nils Wagner
In the study of quantum-mechanical tunneling processes, numerous approaches have been developed to determine the decay rate of states initially confined within a metastable potenti…
Reply to "Clearing up the Strong problem"
Wen-Yuan Ai, Björn Garbrecht, Carlos Tamarit
The conservation of in QCD has been shown to follow from a careful treatment of the path integral and canonical quantization in arXiv:2001.07152 and arXiv:2403.00747. Here, we…
Bubble wall dynamics from nonequilibrium quantum field theory
Wen-Yuan Ai, Matthias Carosi, Bjorn Garbrecht +2
We derive the coupled dynamics between the bubble wall and the plasma from first principles using nonequilibrium quantum field theory. The commonly used equation of motion of the b…
False vacuum decay of excited states in finite-time instanton calculus
Björn Garbrecht, Nils Wagner
Extracting information about a system's metastable ground state energy employing functional methods usually hinges on utilizing the late-time behavior of the Euclidean propagator,…
