Description
In this brief talk I will show how to compute the CFT data and the four-point function in 1D CFTs from unitarity. First I will review the OPE inversion formula, which allows to recover the spectrum and OPE coefficients from the double discontinuity of a Regge bounded four-point function. Then I will explain how to use it to find the CFT data in a perturbative expansion around Generalized Free Field theory. In particular, I will focus on the computation of the contact diagram in theory up to one loop.
