SUMMARY:Daniele Artico: The perturbative bootstrap of the Wilson-line defec
 t CFT - 
DESCRIPTION:Speaker: Daniele Artico\n\nTitle: The perturbative bootstrap o
 f the Wilson-line defect CFT\n\nAbstract:\n\n\nWe study the defect CFT ass
 ociated with the half-BPS Wilson line in N=4 Super Yang-Mills theory in fo
 ur dimensions. Using a perturbative bootstrap approach\, we derive new ana
 lytical results for multipoint correlators of protected defect operators a
 t weak coupling (https://inspirehep.net/literature/2839377) and correlator
 s of one bulk and two defect local operators at strong coupling (https://i
 nspirehep.net/literature/2839381) .\n\nFor multipoint correlators\, we dem
 onstrate that the simplest five- and six-point functions are fully determi
 ned by non-perturbative constraints -- which include superconformal symmet
 ry\, crossing symmetry\, and the pinching of operators to lower-point func
 tions -- as well as by a single integral\, known as the train track integr
 al. For bulk-defect-defect correlators\, we prove that up to NLO the corre
 lator is fully described by boundary integrals\, and that transcendental t
 erms cancel at weak coupling.
