摘要：
We computeM-point conformal blocks with scalar external and exchange operators in the so-called comb configuration for anyMin any dimensiond. Our computation involves repeated use of the operator product expansion to increase the number of external fields. We check our results in several limits and compare with the expressions available in the literature when M = 5 for anyd, and also whenMis arbitrary while d = 1.
