Graviton scattering and a sum rule for the c anomaly in 4D CFT

open access: yesJournal of High Energy Physics, 2018
4D CFTs have a scale anomaly characterized by the coefficient c, which appears as the coefficient of logarithmic terms in momentum space correlation functions of the energy-momentum tensor.

Non-invertible Gauss law and axions

open access: yesJournal of High Energy Physics, 2023
In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries.

Cancellation of the Lorentz anomaly of string field theory in light-cone gauge

open access: yesNuclear Physics B, 1990
Abstract We study the path-integral measure of string fields in the bosonic open-closed interacting string field theory in light-cone gauge. The Lorentz anomaly of the path-integral measure cancels the Lorentz non-invariant terms of the classical string field action. Thus the theory is shown to be Lorentz invariant at the one-loop level. The one-loop

Non-Abelian anomalous (super)fluids in thermal equilibrium from differential geometry

open access: yesJournal of High Energy Physics, 2018
We apply differential geometry methods to the computation of the anomaly-induced hydrodynamic equilibrium partition function. Implementing the imaginary-time prescription on the Chern-Simons effective action on a stationary background, we obtain general ...

’t Hooft anomalies and boundaries

open access: yesJournal of High Energy Physics, 2018
We argue that there is an obstruction to placing theories with ’t Hooft anomalies on manifolds with a boundary, unless the symmetry associated with the anomaly can be represented as a non-invariance under an Abelian transformation.

Boundary conformal anomalies on hyperbolic spaces and Euclidean balls

open access: yesJournal of High Energy Physics, 2017
We compute conformal anomalies for conformal field theories with free conformal scalars and massless spin 1/2 fields in hyperbolic space ℍ d and in the ball Bd $$ {\mathbb{B}}^d $$, for 2≤d≤7. These spaces are related by a conformal transformation.

6D anomaly-free matter spectrum in F-theory on singular spaces

open access: yesJournal of High Energy Physics, 2022
In this paper we study the 6d localized charged matter spectrum of F-theory directly on a singular elliptic Calabi-Yau 3-fold, i.e. without smoothing via resolution or deformation of the entire fibration.

Anomalies of the entanglement entropy in chiral theories [PDF]

open access: yes, 2016
We study entanglement entropy in theories with gravitational or mixed U(1) gauge-gravitational anomalies in two, four and six dimensions. In such theories there is an anomaly in the entanglement entropy: it depends on the choice of reference frame in ...

Scale anomalies, states, and rates in conformal field theory

open access: yesJournal of High Energy Physics, 2017
This paper presents two methods to compute scale anomaly coefficients in conformal field theories (CFTs), such as the c anomaly in four dimensions, in terms of the CFT data.

Geometric general solution to the U(1) anomaly equations

open access: yesJournal of High Energy Physics, 2020
Costa et al. [Phys. Rev. Lett. 123 (2019) 151601] recently gave a general solution to the anomaly equations for n charges in a U(1) gauge theory. ‘Primitive’ solutions of chiral fermion charges were parameterised and it was shown how operations performed
