The scaling dimensions of the operators in this limit may be obtained by a semiclassical saddle point calculation. Using the standard Hubbard-Stratonovich description of the critical O(N) model at large N, we solve the relevant saddle point equation and determine the scaling dimensions as a function of d and   <math> <mover> <mi>j</mi> <mo>\u0302</mo> </mover> </math>  $$ \\hat{j} $$ , finding agreement with all existing results in various limits. In 4 &lt; d &lt; 6, we observe that the scaling dimension of the large charge operators becomes complex above a critical value of the ratio j/N, signaling an instability of the theory in that range of d. Finally, we also derive results for the correlation functions involving two \u201cheavy\u201d and one or two \u201clight\u201d operators. In particular, we determine the form of the \u201cheavy-heavy-light\u201d OPE coefficients as a function of the charges and d."
