DESCRIPTION:Apratim Kaviraj\nIn one of his pioneering works\, Polyakov had
  used conformal symmetries to introduce "unitary amplitudes" that describe
 d a 4-point function. Demanding consistency of the unitary amplitude descr
 iption with the OPE of a correlator\, he could obtain nontrivial data of t
 he operator spectrum. In the modern language\, Polyakov's unitary amplitud
 es seem to emerge from the mellin formalism of conformal field theories. A
  manifestly crossing symmetric mellin transform of a CFT correlator can gi
 ve rise to spurious terms\, not present in the OPE. Demanding the cancella
 tion of the spurious terms lead to nontrivial information of the operators
  of the CFT. Using this approach\, we can obtain various anomalous dimens
 ions and OPE coefficients for both weakly coupled and strongly coupled C
 FTs (including new results for Wilson-Fisher point and the large spin sect
 or).
