1. 1. A CFT perspective on holographic correlators

   Författare :Giulia Fardelli; Agnese Bissi; Paul Heslop; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconformal field theories; Analytic bootstrap; Correlation functions; Quantum gravity; Theoretical Physics; Teoretisk fysik;

   Sammanfattning : Conformal symmetry is ubiquitous in physics. It emerges in a variety of situations from critical phenomena, through condensed matter systems and jets at the LHC to string theory. Conformal field theories (CFTs) describe the universal behavior underlying these very different setups. LÄS MER

3. 2. Maximal Unitarity at Two Loops : A New Method for Computing Two-Loop Scattering Amplitudes

   Författare :Kasper J. Larsen; Lisa Freyhult; David Kosower; Joseph Minahan; Paul Heslop; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amplitudes; NNLO calculations; Quantum Chromodynamics; Unitarity; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : The study of scattering amplitudes beyond one loop is necessary for precision phenomenology for the Large Hadron Collider and may also provide deeper insights into the theoretical foundations of quantum field theory. In this thesis we develop a new method for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. LÄS MER
