✦ Synopsis
In this talk, we describe part of a recent work [1] on the correlation function of a V -A current with a V + A current in the framework of QCD in the limit of a large number of colours N~. The discussion takes place within two successive approximations of this theory, called MHA and MHA+V'. Results concerning the evaluation of chiral condensates of dimension six and eight, as well as matrix elements of the Q7 and Qs electroweak penguin operators, are given.
