I give an overview about the features the Mathematica package SARAH provides to study
new models. In general, SARAH can handle a wide range of models beyond the MSSM …

We investigate the phenomenology of the MSSM extended by a single R-parity-violating
coupling at the unification scale. For all R-parity-violating couplings, we discuss the …

The supersymmetrized DFSZ axion model is highly motivated not only because it offers
solutions to both the gauge hierarchy and strong CP problems, but also because it provides …

We study the sensitivity of the proposed SHiP experiment to the LQD operator in R-parity
violating supersymmetric theories. We focus on single neutralino production via rare meson …

We study the phenomenology associated with a light bino-like neutralino with mass under
the tau mass in the context of the R-parity violating Minimal Supersymmetric Standard …

In string compactifications, frequently the anomalous U (1) gauge symmetry appears which
belongs to E_8 * E_8'E 8× E 8′ of the heterotic string. This anomalous U (1) gauge boson …

We propose a complete R-parity violating supersymmetric model with baryon triality that
contains a Dine-Fischler-Srednicki-Zhitnitsky axion chiral superfield. We parametrize …

An unidentified 3.5 keV line from X-ray observations of galaxy clusters has been reported
recently. Although still under scrutiny, decaying dark matter could be responsible for this …

The QCD axion couplings of various invisible axion models are presented. In particular, the
exact global symmetry U (1) PQ in the superpotential is possible for the anomalous U (1) …

When additional degrees of freedom are considered during inflation, a crucial aspect of
early-universe physics emerges: the generation of isocurvature quantum fluctuations, akin to …
