High energy scattering
Speaker(s): Joao Penedones
Abstract: After defining the Regge limit of the CFT four point function, we shall study the Regge theory that controls the high energy behavior of four point function. In AdS/CFT we can test the Regge theory predictions both at weak and strong coupling. At weak coupling, the leading Regge pole is the well kno... read more

Flat space Limit
Speaker(s): Joao Penedones
Abstract: Using this limit we can extract the scattering amplitudes of the bulk theory in flat space from the correlation functions of the dual CFT. This gives a non-perturbative definition of flat space string theory scattering amplitudes as a limit of the correlation functions of SYM.

Holography from CFT
Speaker(s): Joao Penedones
Abstract: The validity of a local AdS supergravity description of SYM at strong coupling requires the existence of a parametrically large gap in the spectrum of dimensions of the local operators, separating the low dimension operators dual to supergravity fields from the others. We shall give evidence that th... read more
