What is the meaning of spontaneous symmetry breaking?

Spontaneous symmetry breaking is a spontaneous process of symmetry breaking, by which a physical system in a symmetric state ends up in an asymmetric state.

What is physical symmetry?

In physics, a symmetry of a physical system is a physical or mathematical feature of the system (observed or intrinsic) that is preserved or remains unchanged under some transformation. Continuous and discrete transformations give rise to corresponding types of symmetries.

When did electroweak symmetry break?

After electroweak symmetry breaking As a result of this rewriting, the symmetry breaking becomes manifest. In the history of the universe, this is believed to have happened shortly after the hot big bang, when the universe was at a temperature 159.5±1.5 GeV (assuming the Standard Model of particle physics).

What happens to subatomic particles during electroweak symmetry breaking?

The Higgs boson is the particle associated with the mechanism that allows the symmetry of the electroweak force to be broken, or hidden, at low energies and that gives the W and Z particles, the carriers of the weak force, their mass. Numerous other events of this same type with the same net mass have been observed.

How is symmetry broken?

In physics, symmetry breaking is a phenomenon in which (infinitesimally) small fluctuations acting on a system crossing a critical point decide the system’s fate, by determining which branch of a bifurcation is taken. To an outside observer unaware of the fluctuations (or “noise”), the choice will appear arbitrary.

Why is symmetry breaking important?

Symmetry breaking is an important process in both biological evolution and the evolution of the universe as it moves in time through different eras. Wherever structure becomes more complex, symmetry, or at least the original symmetry, is lost.

What is broken symmetry in math?

There are many possible fates for a symmetry. It may be exact, explicitly broken, or dynamically or spontaneously broken. Symmetries arise when a theory has an invariance under some transformation of the basic fields of the theory. This invariance may be either discrete or continuous.
