  1. 1. Cubic Representations of Open-String Effective Action Contact Terms and BCJ Relations at Four-Point One-Loop

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Tegevi Micah; [2021]
    Keywords : Scattering Amplitudes; Color-Kinematics;

    Abstract : 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

  3. 2. A Diagrammatic Study of Gauge and Gravity Amplitude Relations

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Micah Tegevi; [2018]
    Keywords : ;

    Abstract : 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
