摘要
We use the simple instanton motivated Nambu-Jona-Lasinio-type model to calculate a twist 3 pseudoscalar pion light cone wave function psi(pi)(PS). Using the normalization condition for psi(pi)(PS) we calculate the quark condensate and also the gluon condensate, which agree with the phenomenological values for these quantities. Since we can compute also the k(T)(2) dependence of the light cone wave functions, we calculate k(T)(2) moments of the pseudoscalar and axial-vector wave functions which are related to the mixed vacuum condensates. This allows us to extract the condensates and compare them with existing estimates.
