TL;DR

This paper investigates the anomalies associated with a self-dual string in M5-branes, revealing how anomaly cancellation constrains zero-mode anomalies and relates to D-brane couplings through dimensional reduction.

Contribution

It provides a detailed analysis of anomalies in self-dual strings on M5-branes and derives related anomalous couplings for D-branes via dimensional reduction.

Findings

Anomaly cancellation determines zero-mode anomalies and their scaling.

Dimensional reduction links M5-brane anomalies to D-brane couplings.

Results enhance understanding of M5-brane dynamics and anomaly inflow.

Abstract

We study the anomalies of a charge $Q_2$ self-dual string solution in the Coulomb branch of $Q_5$ M5-branes. Cancellation of these anomalies allows us to determine the anomaly of the zero-modes on the self-dual string and their scaling with $Q_2$ and $Q_5$. The dimensional reduction of the five-brane anomalous couplings then lead to certain anomalous couplings for D-branes.
