SUSY Phenomenology - From the Early Universe to the LHC Era
Kersten, Jörn "SUSY Phenomenology---From the Early Universe to the LHC Era" in Particles, Strings and the Early Universe : The Structure of Matter and Space-Time / Haller, Johannes, Grefe, Michael (eds.), Verlag Deutsches Elektronen-Synchrotron : 2018 Hamburg : Verlag Deutsches Elektronen-Synchrotron 271-282 () [10.3204/PUBDB-2018-00782/N1]  GO
If supersymmetry exists around the TeV scale, it affects not only experiments at the LHC but also searches for rare processes, astroparticle physics and cosmology. The goal of the project was to combine information from all these sources in order to learn as much as possible about processes in the early universe and about physics at very high energies that are inaccessible to colliders.

Supernovae Type Ia & Dark Energy
Hauschildt, Peter "Supernovae Type Ia & Dark Energy" in Particles, Strings and the Early Universe : The Structure of Matter and Space-Time / Haller, Johannes, Grefe, Michael (eds.), Verlag Deutsches Elektronen-Synchrotron : 2018 Hamburg : Verlag Deutsches Elektronen-Synchrotron 333-339 () [10.3204/PUBDB-2018-00782/C5]  GO
In project C5 of the SFB 676, we simulated the spectra of cosmological Type Ia supernovae in detail. We use state-of-the-art (3D) NLTE spectral synthesis to analyze the observed multi-wavelength spectra of SNe found in the archives, and make predictions for future observations. [...]

Neutrinos in the Standard Model
Mirizzi, Alessandro "Neutrinos in the Standard Model" in Particles, Strings and the Early Universe : The Structure of Matter and Space-Time / Haller, Johannes, Grefe, Michael (eds.), Verlag Deutsches Elektronen-Synchrotron : 2018 Hamburg : Verlag Deutsches Elektronen-Synchrotron 179-187 () [10.3204/PUBDB-2018-00782/B3]  GO
The project B3 of the SFB 676 has been focussed on theoretical and experimental aspects of low-energy neutrinos from artificial and astrophysical sources. The experimental part consists in the study of the background induced by cosmic muons in current low-energy neutrino experiments. [...]

Non-Abelian Gerbes and some Applications in String Theory
Schweigert, Christoph "Non-Abelian Gerbes and some Applications in String Theory" in Particles, Strings and the Early Universe : The Structure of Matter and Space-Time / Haller, Johannes, Grefe, Michael (eds.), Verlag Deutsches Elektronen-Synchrotron : 2018 Hamburg : Verlag Deutsches Elektronen-Synchrotron 39-55 () [10.3204/PUBDB-2018-00782/A4]  GO
We review a systematic construction of the 2-stack of bundle gerbes via descent, and extend it to non-abelian gerbes. We review the role of non-abelian gerbes in orientifold sigma models, for the anomaly cancellation in supersymmetric sigma models, and in a geometric description of so-called non-geometric T-duals..

TESLA Reports 72 pp. () = Masterarbeit, Warsaw university of technology, 2005
The X-ray free-electron laser XFEL that is being planned at the DESY research center in cooperationwith European partners will produce high-intensity ultra-short X-ray flashes with theproperties of laser light. This new light source, which can only be described in terms of superlatives,will open up a whole range of new perspectives for the natural sciences. [...]
