Celestial two-point functions and rectified dictionary

Celestial two-point functions and rectified dictionary

Abstract A naive celestial dictionary causes massless two-point functions to take the delta-function forms in the celestial conformal field theory (CCFT). We rectify the dictionary, involving the shadow transformation so that the two-point functions follow the standard power-law. In this new definit...
