Tadpole versus anomaly cancellation in D=4,6 compact IIB orientifolds [PDF]
, 1999 It is often stated in the literature concerning D=4,6 compact Type IIB orientifolds that tadpole cancellation conditions i) uniquely fix the gauge group (up to Wilson lines and/or moving of branes) and ii) are equivalent to gauge anomaly cancellation. We

The Holographic Supercurrent Anomaly [PDF]
, 2003 The \gamma-trace anomaly of supersymmetry current in a supersymmetric gauge theory shares a superconformal anomaly multiplet with the chiral R-symmetry anomaly and the Weyl anomaly, and its holographic reproduction is a valuable test to the AdS/CFT ...

The Polyakov loop dependence of bulk viscosity of QCD matter
Nuclear Physics B, 2022 In this work, we show the dependence of bulk viscosity on Polyakov loop in 3+1 dimensional topologically massive model (TMM). This model contains equally massive non-Abelian gauge fields without spontaneous symmetry breaking.

Anomaly freedom in Seiberg-Witten noncommutative gauge theories [PDF]
, 2003 We show that noncommutative gauge theories with arbitrary compact gauge group defined by means of the Seiberg-Witten map have the same one-loop anomalies as their commutative counterparts. This is done in two steps.

Ambitwistor strings in six and five dimensions
Journal of High Energy Physics, 2021 Ambitwistor strings are chiral (holomorphic) strings whose target is the space of complex null geodesics, ambitwistor space. We introduce twistor representations of ambitwistor space in 6 and 5 dimensions.

Galois Action on VOA Gauge Anomalies [PDF]
, 2021 Assuming regularity of the fixed subalgebra, any action of a finite group $G$ on a holomorphic VOA $V$ determines a gauge anomaly $ \in \mathrm{H}^3(G; \boldsymbol )$, where $\boldsymbol \subset \mathbb{C}^\times$ is the group of roots of unity. We show that under Galois conjugation $V \mapsto {^ V}$, the gauge anomaly transforms as $ \mapsto ...

Conformal anomaly from gauge fields without gauge fixing [PDF]
Physical Review D, 2018 We show how the Weyl anomaly generated by gauge fields, can be computed from manifestly gauge invariant and diffeomorphism invariant exact renormalization group equations, without having to fix the gauge at any stage. Regularisation is provided by covariant higher derivatives and by embedding the Maxwell field into a spontaneously broken $U(1|1 ...

17 MeV Atomki anomaly from short-distance structure of spacetime
European Physical Journal C: Particles and Fields, 2020 An anomaly observed recently in the $$^8 \hbox {Be}$$ 8Be nuclear transition by the Atomki collaboration hints at a weakly-coupled, light new gauge boson with a mass of about 17 MeV.

On Gauge Invariance of the Bosonic Measure in Chiral Gauge Theories
Universe, 2021 Gauge invariance of the measure associated with the gauge field is usually taken for granted, in a general gauge theory. We furnish a proof of this invariance, within Fujikawa’s approach.
