Where the article explains it
where is the Euclidean action evaluated on the classical solution that mediates the tunneling — the “bounce” — and A is a prefactor from fluctuations around that solution.
The passage around this formula
where is the Euclidean action evaluated on the classical solution that mediates the tunneling — the “bounce” — and A is a prefactor from fluctuations around that solution. The exponential dependence on the bounce action is the entire reason a metastable vacuum can be, for all practical purposes,…
