Singularities of thermal correlators at strong coupling
Matthew Dodelson, Hirosi Ooguri
We analyze the singularities of the two-point function in a conformal field theory at finite temperature. In a free theory, the only singularity is along the boundary light cone. I…

The High Energy Behavior of Mellin Amplitudes
Matthew Dodelson, Hirosi Ooguri
In any consistent massive quantum field theory there are well known bounds on scattering amplitudes at high energies. In conformal field theory there is no scattering amplitude, bu…

Longitudinal nonlocality in the string S-matrix
Matthew Dodelson, Eva Silverstein
We analyze four and five-point tree-level open string S-matrix amplitudes in the Regge limit, exhibiting some basic features which indicate longitudinal nonlocality, as suggested b…
