Description
Light ray operators control many aspects of Lorentzian physics in quantum field theory. For example, they describe the behavior of correlators at large boost, and also provide a natural basis for collider measurements. Analyticity in spin connects these types of light-ray operators together into an intriguing but still mysterious unified structure. I will review aspects of light-ray operators and some of their applications.
