Chiral symmetry breaking

Chiral symmetry breaking

In particle physics, chiral symmetry breaking is an example of spontaneous symmetry breaking affecting the chiral symmetry of gauge theory such as Quantum Chromodynamics. The origin may be described as a fermion condensate (vacuum condensate of bilinear expressions involving the fermions). The pion decay constant may be viewed as a measure of the magnitude of the chiral symmetry breaking.
