Symmetries and conservation laws of a nonlinear sigma model with gravitino
Jürgen Jost, Enno Keßler, Jürgen Tolksdorf +2
We show that the action functional of the nonlinear sigma model with gravitino considered in a previous article [18] is invariant under rescaled conformal transformations, super We…
Regularity of Solutions of the Nonlinear Sigma Model with Gravitino
Jürgen Jost, Enno Keßler, Jürgen Tolksdorf +2
We propose a geometric setup to study analytic aspects of a variant of the super symmetric two-dimensional nonlinear sigma model. This functional extends the functional of Dirac-ha…
Super Riemann surfaces, metrics, and gravitinos
Jürgen Jost, Enno Keßler, Jürgen Tolksdorf
The underlying even manifold of a super Riemann surface is a Riemann surface with a spinor valued differential form called gravitino. Consequently infinitesimal deformations of sup…
Perturbative Description of the Fermionic Projector: Normalization, Causality and Furry's Theorem
Felix Finster, Jürgen Tolksdorf
The causal perturbation expansion of the fermionic projector is performed with a contour integral method. Different normalization conditions are analyzed. It is shown that the corr…
Bosonic Loop Diagrams as Perturbative Solutions of the Classical Field Equations in -Theory
Felix Finster, Jürgen Tolksdorf
Solutions of the classical -theory in Minkowski space-time are analyzed in a perturbation expansion in the nonlinearity. Using the language of Feynman diagrams, the solution o…
Dirac Type Gauge Theories and the Mass of the Higgs Boson
Juergen Tolksdorf, Torsten Thumstaedter
We discuss the mass of the (physical component of the) Higgs boson in one-loop and top-quark mass approximation. For this the minimal Standard Model is regarded as a specific (para…
