on the higher WZW term in the Green-Schwarz sigma model for the M5-brane.

Abstract We combine rational homotopy theory and higher Lie theory to describe the WZW term in the M5-brane Green-Schwarz sigma model. We observe that this term admits a natural interpretation as a twisted 7-cocycle on super-Minkowski spacetime with coefficients in the rational 4-sphere. This exhibits the WZW term as an element in twisted cohomology, with the twist given by the cocycle of the M2-brane. We consider integration of this rational situation to differential cohomology and differential cohomotopy.
