In CP-violating conformal field theories in four dimensions, the Pontryagin density can appear in the Weyl anomaly. The Pontryagin density in the Weyl anomaly is consistent, but it has a peculiar feature that the parent three-point function of the energy-momentum tensor can violate CP only (semi-)locally. In this paper, we study the supersymmetric completion of the Pontryagin density in the Weyl anomaly, where the central charge $c$ effectively becomes a complex number. The supersymmetry… 

Non-compact duality, super-Weyl invariance and effective actions

In both N $$ \mathcal{N} $$ = 1 and N $$ \mathcal{N} $$ = 2 supersymmetry, it is known that Sp(2 n, ℝ) is the maximal duality group of n vector multiplets coupled to chiral scalar multiplets τ ( x, θ

Trace anomaly for Weyl fermions using the Breitenlohner-Maison scheme for γ*

We revisit the computation of the trace anomaly for Weyl fermions using dimensional regularization. For a consistent treatment of the chiral gamma matrix γ * in dimensional regularization, we work in

Heat kernel and path integrals

We study generalized heat kernel coefficients, which appear in the trace of the heat kernel with an insertion of a first-order differential operator, by using a path integral representation. These

Conformal Contact Terms and Semi-local Terms

We study conformal properties of local terms such as contact terms and semi-local terms in correlation functions of a conformal field theory. Not all of them are universal observables, but they do

Anomalous hydrodynamics with dyonic charge

We study anomalous hydrodynamics with a dyonic charge. We show that the local second law of thermodynamics constrains the structure of the anomaly in addition to the structure of the hydrodynamic

In a September 1976 PRL Eguchi and Freund considered two topological invariants: the Pontryagin number P∼∫d4xgR*R and the Euler number χ∼∫d4xgR*R* and posed the question: to what anomalies do they

CP -violating supersymmetry anomaly

We show that CP-violating Weyl anomaly induces a supersymmetry anomaly in the formulation of superconformal supergravity as is observed in CP-preserving cases. This supersymmetry anomaly can be

Weyl anomalies of four dimensional conformal boundaries and defects

Abstract Motivated by questions about quantum information and classification of quantum field theories, we consider Conformal Field Theories (CFTs) in spacetime dimension d ≥ 5 with a



Supersymmetry on curved spaces and superconformal anomalies

A bstractWe study the consequences of unbroken rigid supersymmetry of four-dimensional field theories placed on curved manifolds. We show that in Lorentzian signature the background vector field

Trace anomalies in chiral theories revisited

A bstractMotivated by the search for possible CP violating terms in the trace of the energy-momentum tensor in theories coupled to gravity we revisit the problem of trace anomalies in chiral

On the trace anomaly of a Weyl fermion in a gauge background

We study the trace anomaly of a Weyl fermion in an abelian gauge background. Although the presence of the chiral anomaly implies a breakdown of gauge invariance, we find that the trace anomaly can be

Noncommutative superspace, Script N = 1/2 supersymmetry, field theory and string theory

We deform the standard four dimensional = 1 superspace by making the odd coordinates θ not anticommuting, but satisfying a Clifford algebra. Consistency determines the other commutation relations of

On renormalization group flows in four dimensions

A bstractWe discuss some general aspects of renormalization group flows in four dimensions. Every such flow can be reinterpreted in terms of a spontaneously broken conformal symmetry. We analyze in
