Baryogenesis, Dark Matter and the Maximal Temperature of the Early Universe
Wilfried Buchmuller
Mechanisms for the generation of the matter-antimatter asymmetry and dark matter strongly depend on the reheating temperature T_R, the maximal temperature reached in the early univ…
Leptogenesis: Theory and Neutrino Masses
Wilfried Buchmuller
After a brief discussion of baryon and lepton number nonconservation, we review the status of thermal leptogenesis with GUT scale neutrino masses, as well as low scale alternatives…
Superconformal D-Term Inflation
W. Buchmüller, V. Domcke, K. Schmitz
We study models of hybrid inflation in the framework of supergravity with superconformal matter. F-term hybrid inflation is not viable since the inflaton acquires a large tachyonic…
Voisin-Borcea Manifolds and Heterotic Orbifold Models
Wilfried Buchmuller, Jan Louis, Jonas Schmidt +1
We study the relation between a heterotic T^6/Z6 orbifold model and a compactification on a smooth Voisin-Borcea Calabi-Yau three-fold with non-trivial line bundles. This orbifold…
Decaying vs Annihilating Dark Matter in Light of a Tentative Gamma-Ray Line
Wilfried Buchmuller, Mathias Garny
Recently reported tentative evidence for a gamma-ray line in the Fermi-LAT data is of great potential interest for identifying the nature of dark matter. We compare the implication…
Spontaneous B-L Breaking as the Origin of the Hot Early Universe
Wilfried Buchmüller, Valerie Domcke, Kai Schmitz
The decay of a false vacuum of unbroken B-L symmetry is an intriguing and testable mechanism to generate the initial conditions of the hot early universe. If B-L is broken at the g…
