Subject: Worldsheet-Induced Corrections to the Holographic Veneziano Amplitude

The Veneziano amplitude is a very useful tool to model meson scattering in confining gauge theories, with many attractive features, namely providing an example of amplitudes with a clear linear Regge trajectory. But this formulation is incomplete- it effectively only exist in theories where the coupling never runs. We expect the Regge trajectory to bend away from linearity due to the running of the coupling at higher energies: we propose a way of doing so, using string theory and the holographic duality, in order to improve on a long-standing result of Makeenko and Olesen.
