Status of the strong problem
Wen-Yuan Ai
The strong problem remains one of the major open questions in the Standard Model of particle physics. Its best-known solution is the Peccei--Quinn mechanism, which predicts a…
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…
Piecewise linear potentials for false vacuum decay and negative modes
Wen-Yuan Ai, Jean Alexandre, Sarben Sarkar
We study bounce solutions and associated negative modes in the class of piecewise linear triangular-shaped potentials that may be viewed as approximations of smooth potentials. In…
