  1. 1. Leading Regge trajectory bosons in the pure spinor formalism

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Erik Raab; [2018]
    Nyckelord :;

    Sammanfattning : We use a map introduced by Berkovits to determine the first levels of the theta-expansion of vertex operators for leading Regge trajectory bosons in the pure spinor formalism. This expansion is then used to confirm that in the pure spinor formalism, the 3-point disc scattering of any leading Regge trajectory bosons reproduces the corresponding Ramond-Neveu-Schwarz result found by Schlotterer.

  3. 2. Constant mean curvature surfaces in hyperbolic 3-space

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Erik Raab; [2014]
    Nyckelord :String theory; hyperbolic 3-space; DPW-method;

    Sammanfattning : The aim of this bachelor's thesis has been to investigate surfaces that are the main contributions to scattering amplitudes in a type of string theory. These are constant mean curvature surfaces in hyperbolic 3-space. Classically the way to find such surfaces has been to solve a non-linear partial differential equation. LÄS MER
