Anomaly interplay in U(2) gauge theories
Journal of High Energy Physics, 2020 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 ...

Anomaly inflow for gauge defects [PDF]
Nuclear Physics B, 1994 Topological defects constructed out of scalar fields and possessing chiral fermion zero modes are known to exhibit an anomaly inflow mechanism which cancels the anomaly in the effective theory of the zero modes through an inflow of current from the space in which the defect is embedded.

Anomaly Inflow and p-Form Gauge Theories [PDF]
Communications in Mathematical Physics, 2022 Chiral and non-chiral $p$-form gauge fields have gravitational anomalies and anomalies of Green-Schwarz type. This means that they are most naturally realized as the boundary modes of bulk topological phases in one higher dimensions. We give a systematic description of the total bulk-boundary system which is analogous to the realization of a chiral ...

A note on gauge anomaly cancellation in effective field theories
Journal of High Energy Physics, 2021 The conditions for the absence of gauge anomalies in effective field theories (EFT) are rivisited. General results from the cohomology of the BRST operator do not prevent potential anomalies arising from the non-renormalizable sector, when the gauge ...

Gauge anomaly cancellation in chiral gauge theories [PDF]
Annals of Physics, 2012 We consider chiral fermions interacting minimally with abelian and non-abelian gauge fields. Using a path integral approach and exploring the consequences of a mechanism of symmetry restoration, we show that the gauge anomaly has null expectation value in the vacuum for both cases (abelian and non-abelian).

Anomalies in the space of coupling constants and their dynamical applications II
SciPost Physics, 2020 We extend our earlier work on anomalies in the space of coupling constants to four-dimensional gauge theories. Pure Yang-Mills theory (without matter) with a simple and simply connected gauge group has a mixed anomaly between its one-form global ...

Instantons, symmetries and anomalies in five dimensions
Journal of High Energy Physics, 2021 All five-dimensional non-abelian gauge theories have a U(1) I global symmetry associated with instantonic particles. We describe an obstruction to coupling U(1) I to a classical background gauge field that occurs whenever the theory has a one-form center

Muon (g − 2) and flavor puzzles in the U(1) X -gauged leptoquark model
Journal of High Energy Physics, 2022 We present an economical model where an S 1 leptoquark and an anomaly-free U(1) X gauge symmetry with X = B 3 − 2L μ /3 − L τ /3 are introduced, to account for the muon anomalous magnetic moment a μ ≡ (g μ − 2) and flavor puzzles including R K ∗ $$ {R}_ ...

Anomalies and symmetry fractionalization
SciPost Physics, 2023 We study ordinary, zero-form symmetry $G$ and its anomalies in a system with a one-form symmetry $\Gamma$. In a theory with one-form symmetry, the action of $G$ on charged line operators is not completely determined, and additional data, a ...
