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…
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…
WIMP Dark Matter from Gravitino Decays and Leptogenesis
Wilfried Buchmüller, Valerie Domcke, Kai Schmitz
The spontaneous breaking of B-L symmetry naturally accounts for the small observed neutrino masses via the seesaw mechanism. We have recently shown that the cosmological realizatio…
