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…
Non-Abelian family symmetries as portals to dark matter
Ivo de Medeiros Varzielas, Oliver Fischer
Non-Abelian family symmetries offer a very promising explanation for the flavour structure in the Standard Model and its extensions. We explore the possibility that dark matter con…
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…
Realising effective theories of tribrid inflation: Are there effects from messenger fields?
Stefan Antusch, David Nolde
Tribrid inflation is a variant of supersymmetric hybrid inflation in which the inflaton is a matter field (which can be charged under gauge symmetries) and inflation ends by a GUT-…
symmetry at colliders and in the universe
Ivo de Medeiros Varzielas, Oliver Fischer, Vinzenz Maurer
Two puzzling facts of our time are the observed patterns in the fermion masses and mixings and the existence of non-baryonic dark matter, which are both often associated with exten…
On the Extraction of Cross Sections for pi0 and eta Photoproduction off Neutrons from Deuteron Data
V. E. Tarasov, W. J. Briscoe, M. Dieterle +4
We discuss the procedure of extracting the photoproduction cross section for neutral pseudoscalar mesons off neutrons from deuteron data. The main statement is that the final-state…
Hill crossing during preheating after hilltop inflation
Stefan Antusch, David Nolde, Stefano Orani
In 'hilltop inflation', inflation takes place when the inflaton field slowly rolls from close to a maximum of its potential (i.e. the 'hilltop') towards its minimum. When the infla…
Testing sterile neutrino extensions of the Standard Model at future lepton colliders
Stefan Antusch, Oliver Fischer
Extending the Standard Model (SM) with sterile ('right-handed') neutrinos is one of the best motivated ways to account for the observed neutrino masses. We discuss the expected sen…
Invariant approach to CP in family symmetry models
Gustavo C. Branco, Ivo de Medeiros Varzielas, Steve F. King
We propose the use of basis invariants, valid for any choice of CP transformation, as a powerful approach to studying specific models of CP violation in the presence of discrete fa…
