SOLARPROP: Charge-sign Dependent Solar Modulation for Everyone
Rolf Kappl
We present SOLARPROP, a tool to compute the influence of charge-sign dependent solar modulation for cosmic ray spectra. SOLARPROP is able to use the output of popular tools like GA…
Modulated Natural Inflation
Rolf Kappl, Hans Peter Nilles, Martin Wolfgang Winkler
We discuss some model-independent implications of embedding (aligned) axionic inflation in string theory. As a consequence of string theoretic duality symmetries the pure cosine po…
AMS-02 Antiprotons Reloaded
Rolf Kappl, Annika Reinert, Martin Wolfgang Winkler
The AMS-02 collaboration has released preliminary data on the antiproton fraction in cosmic rays. The surprisingly hard antiproton spectrum at high rigidity has triggered speculati…
Natural Inflation and Low Energy Supersymmetry
Rolf Kappl, Hans Peter Nilles, Martin Wolfgang Winkler
Natural (axionic) inflation provides a well-motivated and predictive scheme for the description of the early universe. It leads to sizeable primordial tensor modes and thus a high…
