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∗ ≈ ... Web12 de dez. de 2011 · johne1618, As you say, the vacuum expectation value of the Higgs field is v = 246 GeV. It serves to set the scale for the other particle masses induced by the Higgs, for example m W = ½vg where g is one of the weak coupling constants.
