Celestial Conformal Colliders
Yangrui Hu, Sabrina Pasterski
We start by observing that the light-ray operators featured in the conformal collider literature are celestial primaries. This allows us to rephrase the corresponding 4D CFT correl…
Celestial Recursion
Yangrui Hu, Sabrina Pasterski
We examine the BCFW recursion relations for celestial amplitudes and how they inform the celestial bootstrap program. We start by recasting the celestial incarnation of the BCFW sh…
Nonlinear Supersymmetry and 3D Supersymmetric Born-Infeld Theory
Yangrui Hu, Konstantinos Koutrolikos
D-branes acquire effective nonlinear descriptions whose bosonic part is related to the Born-Infeld action. This nonlinearity has been proven to be a consequence of the partial $…
Correlators of Four Light-Ray Operators in CCFT
Shounak De, Yangrui Hu, Akshay Yelleshpur Srikant +1
Building on results in arXiv:2203.04255, we compute the correlator of four gluon light-ray operators in celestial CFT. We find that it is described by Fox H-functions and generaliz…
Four-point correlators of light-ray operators in CCFT
Yangrui Hu, Luke Lippstreu, Marcus Spradlin +2
We compute the four-point correlator of two gluon light-ray operators and two gluon primaries from the four-gluon celestial amplitude in signature spacetime. The correlator…
