The shadow of dark matter as a shadow of string theory: String origin of the dipole term
Rainer Dick
We point out that the Kalb-Ramond field can couple to the Ramond and Neveu-Schwarz fields of superstring theory in a way that can generate a coupling of the Kalb-Ramond field to da…
Crosstalk between DGP branes
Rainer Dick
If two DGP branes carry U(1) gauge theories and overlap, particles of one brane can interact with the photons from the other brane. This coupling modifies in particular the Coulomb…
Coupling of fermionic fields with mass dimensions one to the O'Raifeartaigh model
Kai E. Wunderle, Rainer Dick
The objective of this article is to discuss the coupling of fermionic fields with mass dimension one to the O'Raifeartaigh model to study supersymmetry breaking for fermionic field…
A Supersymmetric Lagrangian for Fermionic Fields with Mass Dimension One
Kai E. Wunderle, Rainer Dick
We present the derivation of a supersymmetric model for fermionic fields with integer valued mass dimension based on a general superfield with one free spinor index. First, we demo…
A photon mass on the brane
R. Dick, D. M. E. McArthur
We discuss the impact of a bulk photon mass in a Dvali-Gabadadze-Porrati type brane model with Maxwell terms both on the brane and in the bulk, as proposed by Dvali, Gabadadze and…
Standard Cosmology in the DGP Brane Model
Rainer Dick
Large extra dimensions provide interesting extensions of our parameter space for gravitational theories. There exist now brane models which can perfectly reproduce standard four-di…
Brane worlds
Rainer Dick
This is an introductory review of gravity on branes with an emphasis on codimension 1 models. However, for a new result it is also pointed out that the cosmological evolution of th…
Which action for brane worlds?
Rainer Dick
In his pioneering work on singular shells in general relativity, Lanczos had derived jump conditions across energy-momentum carrying hypersurfaces from the Einstein equation with c…
Gravity and the Newtonian limit in the Randall-Sundrum model
Rainer Dick, Dzo Mikulovic
We point out that the gravitational evolution equations in the Randall-Sundrum model appear in a different form than hitherto assumed. As a consequence, the model yields a correct…
The string scale and the Planck scale
Rainer Dick
A particle spectrum below the string scale in accordance with predictions from heterotic string theory yields a Planck mass which exceeds the string scale b…
Implications of a dilaton in gauge theory and cosmology
Rainer Dick
After a review of theoretical motivations to consider theories with direct couplings of scalar fields to Ricci and gauge curvature terms, we consider the dynamics and non-perturbat…
The Coulomb potential in gauge theory with a dilaton
Rainer Dick
I calculate the potential of a pointlike particle carrying SU charge in a gauge theory with a dilaton. The solution depends on boundary conditions imposed on the dilaton: Fo…
The dilaton as a candidate for dark matter
Rainer Dick
We examine consequences of the stabilization of the dilaton through the axion. An estimate of the resulting dilaton potential yields a relation between the axion parameter $m_a f_{…
Self-trapping of the dilaton
Rainer Dick
The dilaton in three dimensions does not roll. Witten's conjecture that duality between theories in three and four dimensions solves the cosmological constant problem thus may also…
Remarks on chiral symmetry breaking with massless fermions
Rainer Dick
In this talk I present recent results on Lorentz covariant correlation functions on the cone . In particular, chiral symmetry breaki…
Half-Differentials and Fermion Propagators
Rainer Dick
From a geometric point of view, massless spinors in dimensions are composed of primary fields of weights and , where the weights are define…
Non-Standard Fermion Propagators from Conformal Field Theory
Rainer Dick
It is shown that Weyl spinors in 4D Minkowski space are composed of primary fields of half-integer conformal weights. This yields representations of fermionic 2-point functions in…
