WebThe Higgs field has a vacuum expectation value of 246 GeV. [1] This nonzero value underlies the Higgs mechanism of the Standard Model. This value is given by , where MW is the mass of the W Boson, the reduced Fermi constant, and g the weak isospin coupling, in natural units. It is also near the limit of the most massive nuclei, at v = 264.3 Da.

Effective field theories typically work best when there is a large separation between length scale of interest and the length scale of the underlying dynamics. Effective field theories have found use in particle physics, statistical mechanics, condensed matter physics, general relativity, and hydrodynamics.

To picture it, “we think of the totality of space as being this 3-D mattress,” Dimopoulos said. The value at each point in the field corresponds to how compressed the mattress springs are there.
WebIn physics, specifically field theory and particle physics, the Proca action describes a massive spin -1 field of mass m in Minkowski spacetime. The corresponding equation is a relativistic wave equation called the Proca equation. [1] The Proca action and equation are named after Romanian physicist Alexandru Proca .
