Cubic Representations of Open-String Effective Action Contact Terms and BCJ Relations at Four-Point One-Loop
The tree amplitudes of string theory low-energy effective actions admit a diagrammatic expansion in terms of higher-than-cubic contact terms. These tree amplitudes can be used to build loop amplitudes using unitary cuts or the forward limit. In this thesis we study the possibility of constructing fo...
