Tom Banks, Rutgers, HEP Seminar, Do Conformal Field Theory Correlators Compute the Non-perturbative Minkowski S Matrix? (2:00 PM - 3:00 PM, 726 Broadway, 940, CCPP Seminar)

-- Description: I present two independent arguments that the answer to the question in the title is NO. The first involves the Tensor Network Renormalization Group approach to local physics in AdS space. I show that it provides a derivation of the Holographic Space-time (HST) formalism for the special case of AdS space, but only on scales of order the AdS radius or larger. For smaller scales (in models with a large radius gravity dual), TNRG does not reproduce the scrambling properties of small black holes. The HST formalism does reproduce those properties, but that physics is unconnected to the time evolution defined by the CFT Hamiltonian. An independent argument comes from the claim that the Minkowski scattering operator in never unitary in the Fock space of gravitons. This is manifestly true in four dimensions, where all Fock space matrix elements vanish, but true non-perturbatively in higher dimensions as well. CFT correlators can compute at most the finite Fock space matrix elements, when they exist. If time permits, I'll discuss the connection between these arguments. In HST the majority of states in a causal diamond in Minkowski space, describe "soft gravitons propagating on the boundary of the diamond" and the Hamiltonian of these states is invariant under volume preserving maps of the holographic screen of the diamond. In order to describe the conformal boundary of AdS space, the Hamiltonian for diamonds whose proper time is of order the AdS radius or larger must break this symmetry in order to properly converge to the boundary field theory Hamiltonian. This is naturally incorporated in the formalism of HST because the Hamiltonian is time dependent, reflecting the fact that the time slices are always taken to lie inside the past light cone of a point on a particular time-like trajectory.
