We survey anomalies of discrete symmetries in heterotic orbifolds and find a new relation between such anomalies and the socalled ‘anomalous ’ U(1). We follow the discussion of , and extend it such as to include gravitational anomaly constraints. Abstract: J54.00009: Non-Abelian anomalies in multi-Weyl semimetals Abstract . We show that the discrete anomaly constraints governing popular non-Abelian symmetries of use in (e.g.) One of our main re-sults is the generalization of anomalous Hall e ect for multi-Weyl semimetals, and its non-Abelian variation, Such a tenuous symmetry is said to be "anomalous," beset by a "quantum symmetry anomaly." Such an SU(2) field preserves certain crystalline symmetry (fourfold rotational or C4 in our construction), but breaks the Lorentz symmetry, resulting in nonlinear band spectra, namely, E∼(p2x+p2y)n/2, but E∼|pz|, for example, where momenta p is measured from the Weyl nodes. We consider the hypothesis that the C-field 4-flux and 7-flux forms in M-theory are in the image of the non-abelian Chern character map from the non-abelian generalized cohomology theory called J-twisted Cohomotopy theory. The relationship between the phenomenon of species doubling on the lattice and the Abelian anomaly is generalized to the case of the non-Abelian anomaly. 2.

The non-Abelian anomaly, its nonrenormalization and geometric interpretation. Consequently, the effective field theory displays U(1)×SU(2) non-Abelian anomalies, yielding the anomalous Hall effect, its non-Abelian generalization, and various chiral conductivities. These predictions are also supported from a strongly coupled (holographic) description of MWSMs. We discuss in detail the relation between anomaly, current non-conservation and non-invariance of the e ective action, with special emphasis on the derivation of the anomalous Slavnov-Taylor/Ward identities. We survey anomalies of discrete symmetries in heterotic orbifolds and find a new relation between such anomalies and the so-called ‘anomalous’ U(1).We use cookies to help provide and enhance our service and tailor content and ads.
