Black Holes and Conformal Regge Bootstrap

Understand

Highly energetic particles traveling in the background of an asymptotically AdS black hole experience a Shapiro time delay and an angle deflection.

• These quantities are related to the Regge limit of a heavy-heavy-light-light four-point function of scalar operators in the dual CFT.
• The Schwarzschild radius of the black hole in AdS units is proportional to the ratio of the conformal dimension of the heavy operator and the central charge.
• This ratio serves as a useful expansion parameter; its power counts the number of stress tensors in the multi-stress tensor operators which contribute to the four-point function.
