DESCRIPTION:Speakers: Yue-Zhou Li (Prinston U)\n\nI will talk about light-
 ray operators in QFTs\, with particular emphasis on the critical O(N) mode
 l and on the leading-twist and horizontal Regge trajectories. Conceptually
 \, I will distinguish between light-ray operators in two conformal frames:
  detectors\, which characterize event shapes\, and distributions\, which p
 robe initial-state properties. This bridges the language to perturbative Q
 CD\, including parton distribution functions and collinear (jet) functions
 . I will then discuss the renormalization of horizontal distributions in t
 he O(N) model. In addition\, I will discuss the renormalization of detecto
 r operators in the O(N) model\, explaining how the mixing between the lead
 ing-twist operator and its shadow can be resolved to determine the Pomeron
  spin. Finally\, I will comment on distribution and detector operators in 
 QCD\, as well as a celestial defect detector whose renormalization is cont
 rolled by the BK equation.\n\nhttps://indico.bnl.gov/event/32494/
