Query: Is there the color-flavor locking in the instanton induced
  quark-antiquark pairing in QCD vacuum?   By means of the functional integral method we show that in the case of the
quark-antiquark pairing at zero temperature and zero chemical potential (in the
vacuum) the singlet pairing is more preferable than that with the color-flavor
locking (CFL)
