Cyclic unparticle physics
Jean-François Fortin, Benjamin Grinstein, Andreas Stergiou
We explore phenomenological consequences of coupling a non-conformal scale-invariant theory to the standard model. We point out that, under certain circumstances, non-conformal sca…
Superconformally Covariant OPE and General Gauge Mediation
Jean-François Fortin, Kenneth Intriligator, Andreas Stergiou
We consider using broken superconformal symmetry and the super operator product expansion (sOPE) to constrain and analyze hidden sector theories that couple to our gauge forces and…
Scale without Conformal Invariance: Theoretical Foundations
Jean-François Fortin, Benjamín Grinstein, Andreas Stergiou
We present the theoretical underpinnings of scale without conformal invariance in quantum field theory. In light of our results the gradient-flow interpretation of renormalization-…
Current OPEs in Superconformal Theories
Jean-François Fortin, Kenneth Intriligator, Andreas Stergiou
It's well known that in conformal theories the two- and three-point functions of a subset of the local operators-the conformal primaries-suffice, via the operator product expansion…
Scale without Conformal Invariance: An Example
Jean-François Fortin, Benjamín Grinstein, Andreas Stergiou
We give an explicit example of a model in D=4-epsilon space-time dimensions that is scale but not conformally invariant, is unitary, and has finite correlators. The invariance is a…
