The Green-Schwarz mechanism and geometric anomaly relations in 2d (0,2) F-theory vacua
The Green-Schwarz mechanism and geometric anomaly relations in 2d (0,2) F-theory vacua
We study the structure of gauge and gravitational anomalies in 2d N=(0,2) theories obtained by compactification of F-theory on elliptically fibered Calabi-Yau 5-folds. Abelian gauge anomalies, induced at 1-loop in perturbation theory, are cancelled by a generalized Green-Schwarz mechanism operating at the level of chiral scalar fields in the 2d …
