Webelectroweak Higgs vacuum to the true vacuum (with large negative energy density) is dominated by the Hawking-Moss instanton [21]. This corresponds to a process in which the Higgs field across the the entire inflationary patch develops a large expectation value equal to the top of the potential barrier separating false and true vacua, h∗ ≈ ...
