R symmetries and a heterotic MSSM
Rolf Kappl, Hans Peter Nilles, Matthias Schmitz
We employ powerful techniques based on Hilbert- and Groebner bases to analyze particle physics models derived from string theory. Individual models are shown to have a huge landsca…
The Cosmic Ray Antiproton Background for AMS-02
Rolf Kappl, Martin Wolfgang Winkler
The AMS-02 experiment is measuring the cosmic ray antiproton flux with high precision. The interpretation of the upcoming data requires a thorough understanding of the secondary an…
Aligned Natural Inflation: Monodromies of two Axions
Rolf Kappl, Sven Krippendorf, Hans Peter Nilles
Natural (axionic) inflation can accommodate sizeable primordial tensor modes but suffers from the necessity of trans-Planckian variations of the inflaton field. This problem can be…
