Z-string global gauge anomaly and Lorentz non-invariance [PDF]
Certain (3+1)-dimensional chiral non-Abelian gauge theories have been shown to exhibit a new type of global gauge anomaly, which in the Hamiltonian formulation is due to the fermion zero-modes of a Z-string-like configuration of the gauge potential and ...

Quantization of anomaly coefficients in 6D N=1,0 $$ \mathcal{N}=\left(1,\;0\right) $$ supergravity
We obtain new constraints on the anomaly coefficients of 6D N=10 $$ \mathcal{N}=\left(1,0\right) $$ supergravity theories using local and global anomaly cancellation conditions.

Comments on QCD3 and anomalies with fundamental and adjoint matter
’t Hooft anomaly matching is powerful for constraining the low energy phases of gauge theories. In 3d one common anomaly is the parity anomaly in a T-symmetric theory where one cannot gauge the global symmetry group without breaking the time-reversal ...

Discrete anomaly matching for the Pouliot type dualities
We compute the 't Hooft anomalies of discrete symmetries in the Pouliot type dual theories and check their anomaly matching conditions. The Pouliot type dual theories we will consider in this paper are two dual pairs; the dual pair of N=1 supersymmetric ...

Anomaly interplay in U(2) gauge theories
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 ...

A note on gauge anomaly cancellation in effective field theories
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 ...

Anomalies in the space of coupling constants and their dynamical applications II
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
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
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}_ ...
