We quantify the impact of gauge anomalies at the Large Hadron Collider bystudying the invariant mass distributions in Drell-Yan and in double promptphoton, using an extension of the Standard Model characterized by an additionalanomalous U(1) derived from intersecting branes. The approach is rather generaland applies to any anomalous abelian gauge current. Anomalies are cancelledusing either the Wess-Zumino mechanism with suitable Peccei-Quinn-likeinteractions and a Stueckelberg axion, or by the Green-Schwarz mechanism. Wecompare predictions for the corresponding extra Z-prime to anomaly-freerealizations such as those involving U(1)_{B-L}. We identify the leadinganomalous corrections to both channels, which contribute at higher orders, andcompare them against the next-to-next-to-leading order (NNLO) QCD background.Anomalous effects in these inclusive observables are found to be very small,far below the percent level and below the size of the typical QCD correctionsquantified by NNLO K-factors.
