Abstract
The correlation function of a current with a current is discussed within the framework of QCD in the limit of a large number of colours . Applications to the evaluation of chiral condensates of dimension six and higher, as well as to the matrix elements of the and electroweak penguin operators are discussed. A critical comparison with previous determinations of the same parameters has also been made.
