Description |
We take a simple step towards implementing the causality constraint in the CFT by exploiting connection between unitarity, causality and crossing symmetry. Most of our computation is restricted to scalar correlators and we show that causality constrains the sign of certain non-analytic terms in conformal block expansion. We also discuss connection with dual gravity computation. |
