摘要：
We extend the method of QCD sum rules in external fields to determine the rho NN and omega NN strong couplings, including both the vector and tensor couplings. Such information has been used for years in the construction of nuclear potentials, but our attempt represents the first direct contact with QCD in terms of the basic parameters associated with the nontrivial QCD vacuum.
