Higgs production from sterile neutrinos at future lepton colliders
Stefan Antusch, Eros Cazzato, Oliver Fischer
In scenarios with sterile (right-handed) neutrinos that are subject to an approximate "lepton-number-like" symmetry, the heavy neutrinos (i.e. the mass eigenstates) can have masses…
Predicting the Sparticle Spectrum from GUTs via SUSY Threshold Corrections with SusyTC
Stefan Antusch, Constantin Sluka
Grand Unified Theories (GUTs) can feature predictions for the ratios of quark and lepton Yukawa couplings at high energy, which can be tested with the increasingly precise results…
Impact of other scalar fields on oscillons after hilltop inflation
Stefan Antusch, Stefano Orani
Oscillons are spatially localized and relatively stable field fluctuations which can form after inflation under suitable conditions. In order to reheat the universe, the fields whi…
Parametric resonance after hilltop inflation caused by an inhomogeneous inflaton field
Stefan Antusch, Francesco Cefala, David Nolde +1
We study preheating after hilltop inflation where the inflaton couples to another scalar field, e.g. a right-handed sneutrino, which provides a mechanism for generating the correct…
One-Loop Right-Handed Neutrino Threshold Corrections for Two-Loop Running in Supersymmetric Type I Seesaw Models
Stefan Antusch, Eros Cazzato
The renormalization group (RG) running of the neutrino mass operator is required for comparing the predictions of neutrino models at high energy with the experimental data at low e…
Non-thermal Gravitino Production in Tribrid Inflation
Stefan Antusch, Koushik Dutta
We investigate non-thermal gravitino production after tribrid inflation in supergravity, which is a variant of supersymmetric hybrid inflation where three fields are involved in th…
