Open AccessSuperspace formulation of the local RG equation
We present the superspace formulation of the local RG equation, a framework for the study of supersymmetric RG flows in which the constraints of holomorphy and R-symmetry are manifest. We derive the consistency c...

Open AccessThe local RG equation and chiral anomalies
We generalize the local renormalization group (RG) equation to theories with chiral anomalies. We find that a new anomaly is required by the Wess-Zumino consistency conditions. Taking into account the new anom...

Open AccessThe local Callan-Symanzik equation: structure and applications
The local Callan-Symanzik equation describes the response of a quantum field theory to local scale transformations in the presence of background sources. The consistency conditions associated with this anomalo...

The dilaton Wess-Zumino action in higher dimensions
We present a general formula for the Wess-Zumino action associated with the Weyl anomaly, given in a curved background for any even number of dimensions. The result is obtained by considering a finite Weyl tra...

Supersymmetric sound in fluids
We consider the hydrodynamics of supersymmetric fluids. Supersymmetry is broken spontaneously and the low energy spectrum includes a fermionic massless mode, the phonino. We use two complementary approaches to de...

Hydrodynamics and the detection of the QCD axial anomaly in heavy ion collisions
We consider the experimental implications of the axial current triangle diagram anomaly in a hydrodynamic description of high density QCD. We propose a signal of an enhanced production of spin-excited hadrons ...
