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. The double-copy method for supergravity amplitudes
University essay from Uppsala universitet/Teoretisk fysikAbstract : The double-copy construction enables the calculation of scattering amplitudes in theories of gravity by combining amplitudes from gauge theories. It relies on obtaining numerators that obey a duality between color and numerator factors, called color-kinematics duality. READ MORE

3. A Diagrammatic Study of Gauge and Gravity Amplitude Relations
University essay from Uppsala universitet/Teoretisk fysikAbstract : We review modern methods of scattering amplitude computations, beginning with color-decomposition that decomposes the amplitude into a color-dependentand a color-independent part of partial color-ordered amplitudes. We then show how a full amplitude can be described through the color-factor, propagator structure, and kinematic numerator of cubic color-ordered diagrams. READ MORE
