WebApr 27, 2024 · The all-loop resummation of SU$(N)$ gauge theory amplitudes is known to factorize into an IR-divergent (soft and collinear) factor and a finite (hard) piece. The divergent factor is universal, whereas the hard function is a process-dependent quantity. We prove that this factorization persists for the corresponding celestial amplitudes. … Web2 Celestial amplitudes in N = 4 SYM. 2.1 Review of the BDS Ansatz; 2.2 IR divergences in celestial n-point correlators; 2.3 BDS celestial amplitude; 2.4 Divergent part as a conformal correlator; 2.5 Finite part: The UV and the positivity of the cusp anomalous dimension. 2.5.1 Four gluons; 2.5.2 Five gluons; 3 Infrared divergences in gluon ... scp fontanet cherbourg https://adventourus.com
