Abstract: After inserting the heavy quark mass dependence into QCD partonic evolutionequations, we determine the mean charged hadron multiplicity and secondmultiplicity correlators of jets produced in high energy collisions. We therebyextend the so-called dead cone effect to the phenomenology of multiparticleproduction in QCD jets and find that the average multiplicity of heavy-quarkinitiated jets decreases significantly as compared to the massless case, eventaking into account the weak decay products of the leading primary quark. Weemphasize the relevance of our study as a complementary check of $b$-taggingtechniques at hadron colliders like the Tevatron and the LHC.
