SUMMARY:Light-ray operators and higher-twist Regge traject
 ories in conformal field theory - Petr Kravchuk\,

DESCRIPTION: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 cor
 relators in conformal collider physics. However\, 
 the precise way in which this analyticity is reali
 zed in concrete theories remains mysterious\, espe
 cially at subleading twist. In this talk I will de
 scribe an ongoing work to understand Regge traject
 ories in the example of Wilson-Fisher theory in 4-
 epsilon expansion\, as well as a general mechanism
  that reconciles spin analyticity with spin-depend
 ent degeneracy of local operators.
