Scale Invariance + Unitarity => Conformal Invariance?
Particle Physics - Theory | High Energy Physics - Phenomenology | Condensed Matter - Statistical Mechanics | High Energy Physics - Theory
We revisit the long-standing conjecture that in unitary field theories, scale invariance implies conformality. We explain why the Zamolodchikov-Polchinski proof in D=2 does not work in higher dimensions. We speculate which new ideas might be helpful in a future proof. W...
