In this note we demonstrate that, as we conjectured earlier in [1], the a-charge in the conformal anomaly in dimension d=2n manifests in a n-point correlation function of energy momentum tensor of a CFT considered in flat spacetime with a conical defect. We consider in detail dimensions d=2,4,6 and give a general formula for arbitrary n.
