Anomaly interplay in U(2) gauge theories
Abstract We discuss anomaly cancellation in U(2) gauge theories in four dimensions. For a U(2) gauge theory defined with a spin structure, the vanishing of the bordism group Ω 5 Spin $$ {\Omega}_5^{\mathrm{Spin}} $$ (BU(2)) implies that there can be no global anomalies, in contrast to the related ca...
