It turns out, however, that these two problems in a sense “cancel out”.

The condensate will then define a preferred phase, and the phase of the condensate will define the zero value of the field in a gauge-invariant way. Ernst Stueckelberg discovered [32] a version of the Higgs mechanism by analyzing the theory of quantum electrodynamics with a massive photon. The Meissner effect is due to currents in a thin surface layer, whose thickness, the London penetration depthcan be calculated from a simple model the Ginzburg—Landau theory.

The second term is the extra potential energy when the field varies from point to point. For the U 1 gauge theory, if one wants a formulation in terms of a Hilbert space containing only physical states, this cannot be done in a manifestly covariant way. This was mysterious for a long time, because it implies that electromagnetic forces somehow become short-range inside the superconductor.


Das Feld selbst entzieht sich der direkten Beobachtung.

Journal of Experimental and Theoretical Physics. It is important to note that most of the mass of the nucleon in particular does not arise in this way.

The Higgs mechanism occurs whenever a charged field has a vacuum expectation value. The mechanism is closely analogous to phenomena previously discovered by Yoichiro Nambu involving the “vacuum structure” of quantum fields in superconductivity. Depending on the representation of the scalar field, not every gauge field acquires a mass. Contents 1 Role of the mechanism 2 Spontaneous symmetry breaking 2.

There are two massive W mesons in the Schwinger model, with a mass set by the mass scale Aand one massless U 1 gauge boson, similar to the photon.

Under U 1 rotations, it is multiplied by a phase, which thus mixes the real and imaginary parts of the complex spinor into each other, combining to the standard two-component complex representation of the group U 2.

Stock like only Adobe can. However, their paper was delayed by the editorial office of JETPand was published late, in The first term here is merely an unimportant constant.


Archived from the original on In general, models involving massive vector fields are non-renormalizable. Higgs – teilchen – 3D Render fotoliaxrender Fotolia. The first term is the kinetic energy of the field. The theory of quantum electrodynamics with a massive photon is still a renormalizable theory, one in which electric charge is still conserved, but magnetic monopoles are not allowed.

For the Goldstone model, the situation is different. But this is not the case for a field theory in infinite volume. Family Moments with loved ones. Strahlentherapie CrazyCloud Fotolia.
