Query: Anomaly Poles as Common Signatures of Chiral and Conformal Anomalies   One feature of the chiral anomaly, analyzed in a perturbative framework, is
the appearance of massless poles which account for it. They are identified by a
spectral analysis of the anomaly graph and are usually interpreted as being of
an infrared origin. Recent investigations show that their presence is not just
confined in the infrared, but that they appear in the effective action under
the most general kinematical conditions, even if they decouple in the infrared.
Further studies reveal that they are responsible for the non-unitary behaviour
of these theories in the ultraviolet (UV) region. We extend this analysis to
the case of the conformal anomaly, showing that the effective action describing
the interaction of gauge fields with gravity is characterized by anomaly poles
that give the entire anomaly and are decoupled in the infrared (IR), in
complete analogy with the chiral case. This complements a related analysis by
Giannotti and Mottola on the trace anomaly in gravity, in which an anomaly pole
has been identified in the corresponding correlator using dispersion theory in
the IR. Our extension is based on an exact computation of the off-shell
correlation function involving an energy-momentum tensor and two vector
currents (the gauge-gauge-graviton vertex) which is responsible for the
appearance of the anomaly.
