Metastable vacuum decay and θ dependence in gauge theory. Deformed QCD as a toy model
We study a number of different ingredients related to the θ dependence, metastable excited vacuum states and other related subjects using a simplified version of QCD, the so-called “deformed QCD”. This model is a weakly coupled gauge theory, which, however, preserves all the relevant essential eleme...
