Gluon condensate

Template:Short description Template:One source In quantum chromodynamics (QCD), the gluon condensate is a non-perturbative property of the QCD vacuum which could be partly responsible for giving masses to light mesons.

If the gluon field tensor is represented as G_μν, then the gluon condensate is the vacuum expectation value $⟨G_{\mu \nu }{G}^{\mu \nu }⟩$. It is not clear yet whether this condensate is related to any of the known phase changesTemplate:Which in quark matter. There have been scattered studies of other types of gluon condensates, involving a different number of gluon fields.

For more on the context in which this quantity occurs, see the article on the QCD vacuum.
