SUMMARY:Light-ray operators and higher-twist Regge trajectories in conform
 al field theory - Petr Kravchuk\, King's College London

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 correlators in conformal collider physics. However\, the precis
 e way in which this analyticity is realized in concrete theories remains m
 ysterious\, especially at subleading twist. In this talk I will describe a
 n ongoing work to understand Regge trajectories in the example of Wilson-F
 isher theory in 4-epsilon expansion\, as well as a general mechanism that 
 reconciles spin analyticity with spin-dependent degeneracy of local operat
 ors.
