fermionic condensate

(redirected from Quark condensate)

fermionic condensate:

see condensatecondensate,
matter in the form of a gas of atoms, molecules, or elementary particles that have been so chilled that their motion is virtually halted and as a consequence they lose their separate identities and merge into a single entity.

In this approach, the quark-gluon language and Wilson operator product expansion (OPE) are usually used to evaluate the correlation function in terms of the QCD degrees of freedom such as quark condensate, gluon condensate, etc.

The input parameters used in the above coefficients include the strange quark mass and quark condensates. In our numerical calculations, we use the following values of these parameters (see [3,11,12]):
We should stress that the contributions of the light quark condensates are eliminated by applying the double Borel transformations with respect to the initial and final momenta; hence, in the [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] functions we only consider the two-gluon condensate contributions.

Hence, contributions of the light quark condensates {diagrams shown in Figures 1(b), 1(c), and 1(d)} vanish by applying the double Borel transformations [16].
