Abstract
Quark-antiquark condensation has been investigated in the framework of the NJL model. Using the Fermi momentum of the particle as cut-off parameter the gap energy and coherence length for meson condensates have been studied. The Fermi momentum for the \(\left\langle {q\bar q} \right\rangle\) condensate has been extracted considering the coherence length ξ ∼ 1 fm. The results are compared with existing data. Some interesting observations are made.
