  1. 1. Anomalous Dimensions in the WF O(N) Model with a Monodromy Line Defect

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Alexander Söderberg; [2017]
    Keywords : Anomalous Dimensions; WF; O N Model; phi^4 theory; Monodromy Line Defect; Co-Dimension Two; 3 Dimensions; CFT; 3D; Dimensional; Conformal Field Theory; Quantum Field Theory; QFT;

    Abstract : General ideas in the conformal bootstrap program are covered. Both numerical and analytical approaches to the bootstrap equation are reviewed to show how it can be manipulated in different ways. Further analytical approaches are studied for theories with defects. READ MORE

  2. 2. Transverse Momentum Dependent Soft Function in SCET to NNLO

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Joel Oredsson; [2015]
    Keywords : renormalization; soft collinear effective field theory; SCET; effective theory; NNLO; Higgs; QCD; precision calculations; loop calculations; Physics and Astronomy;

    Abstract : We review the factorization theorem for the production of a heavy color-neutral final state with a transverse momentum much smaller than its invariant mass in the framework of soft collinear effective field theory (SCET). This phase space region is plagued by large logarithms of widely separated scales, including large logarithms of rapidity ratios, that need to be resummed for sensible results. READ MORE
