Critical flavour number of the Thirring model in three dimensions
Björn H. Wellegehausen, Daniel Schmidt, Andreas Wipf
The Thirring model is a four-fermion theory with a current-current interaction and chiral symmetry. It is closely related to three-dimensional QED and other models used to…
Four-Fermion Theories with Exact Chiral Symmetry in Three Dimensions
Daniel Schmidt, Björn Wellegehausen, Andreas Wipf
We investigate a class of four-fermion theories which includes well-known models like the Gross-Neveu model and the Thirring model. In three spacetime dimensions, they are used to…
Critical flavour number of the Thirring model in three dimensions
Daniel Schmidt, Björn Wellegehausen, Andreas Wipf
The Thirring model is a four fermion theory with vector interaction. We study it in three dimensions, where it is closely related to QED and other models used to describe propertie…
Status of the Zee-Babu model for neutrino mass and possible tests at a like-sign linear collider
Daniel Schmidt, Thomas Schwetz, He Zhang
We provide an updated scan of the allowed parameter space of the two-loop Zee-Babu model for neutrino mass. Taking into account most recent experimental data on as well a…
Curvature-induced Resolution of Anti-brane Singularities
Daniel Junghans, Daniel Schmidt, Marco Zagermann
We study AdS vacua of massive type IIA string theory compactified on a 3-sphere with flux and anti-D6-branes. In such backgrounds, the anti-brane backreaction is known to…
Dark matter and U(1)' symmetry for the right-handed neutrinos
Manfred Lindner, Daniel Schmidt, Atsushi Watanabe
We consider a U(1)' gauge symmetry acting on three generations of right-handed neutrinos. The U(1)' symmetry is broken at the TeV scale and its remnant discrete symmetry makes one…
