Analyticity in spin and Regge trajectories play a central role in many CFT observables, such as the Regge limit of four-point functions or energy correlators in conformal collider physics. However, the precise way in which this analyticity is realized in concrete theories remains mysterious, especially at subleading twist. In this talk I will describe an ongoing work to understand Regge trajectories in the example of Wilson-Fisher theory in 4-epsilon expansion, as well as a general mechanism that reconciles spin analyticity with spin-dependent degeneracy of local operators.
