Supersymmetric Dark Matter Candidates - The Lightest Neutralino, the Gravitino, and the Axino
Frank Daniel Steffen
In supersymmetric extensions of the Standard Model, the lightest neutralino, the gravitino, and the axino can appear as the lightest supersymmetric particle and as such provide a c…
CBBN in the CMSSM
Josef Pradler, Frank Daniel Steffen
Catalyzed big bang nucleosynthesis (CBBN) can lead to an overproduction of ^6Li in gravitino dark matter scenarios in which the lighter stau is the lightest Standard Model superpar…
Implications of Catalyzed BBN in the CMSSM with Gravitino Dark Matter
Josef Pradler, Frank Daniel Steffen
We investigate gravitino dark matter scenarios in which the primordial ^6Li production is catalyzed by bound-state formation of long-lived negatively charged particles X^- with ^4H…
Supersymmetric Candidates for Dark Matter (in German)
Frank Daniel Steffen
The identity of dark matter is one of the greatest puzzles of our Universe. Its solution may be associated with supersymmetry which is a fundamental space-time symmetry that has no…
