This discusses how differential cohomology – specifically ordinary differential cohomology and differential K-theory – is the correct formalism for describing gauge fields and higher gauge fields in physics and string theory (such as higher U(1)-gauge fields like the electromagnetic field, the Kalb-Ramond field and the supergravity C-field, and also the RR-field) and the quantum anomaly of their action functionals.
