1. Cubic Representations of Open-String Effective Action Contact Terms and BCJ Relations at Four-Point One-Loop
University essay from Uppsala universitet/Teoretisk fysikAbstract : 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. READ MORE

2. Browsing the Web of Amplitudes
University essay from Uppsala universitet/Teoretisk fysikAbstract : We begin by studying field-theory amplitude relations such as the Kleiss-Kuijf, Bern-Carrasco-Johansson, Kawai-Lewellen-Tye and the double copy construction, which are important ingredients in this thesis. Going beyond the field-theory limit we study how the gauge-sector of the heterotic string relates to type I amplitudes through the single valued projection of multiple zeta values. READ MORE
