Contribution

It provides a comprehensive review of exact results on interpolating quantum field theories, covering both supersymmetric and non-supersymmetric cases.

Findings

Exact relations for central charges in interpolating theories

Results on anomalous dimensions at fixed points

Insights into quantum irreversibility in these theories

Abstract

I review recent results on conformal field theories in four dimensions and quantum field theories interpolating between conformal fixed points, supersymmetric and non-supersymmetric. The talk is structured in three parts: i) central charges, ii) anomalous dimensions and iii) quantum irreversibility.
