Higher Flavor Symmetries in the Standard Model
Annalen der Physik, Volume 535, Issue 8, August 2023., 2023 The Standard Model enjoys a higher‐group symmetry which mixes the zero‐form flavor symmetries with the one‐form magnetic hyper charge symmetry. This structure greatly restricts the possible flavor symmetries that may remain unbroken in any ultraviolet completion that includes magnetic monopoles.

The Low‐Scale Seesaw Solution to the MW$M_W$ and (g−2)μ$(g-2)_\umu$ Anomalies
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract The recent CDF‐II measurement of the W‐boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the context of the Low‐Scale Seesaw mechanisms, this tension can be resolved.

Probing HNL‐ALP Couplings at Colliders
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract Axion‐like particles (ALPs) and heavy neutral leptons (HNLs) are both well‐motivated extensions of the Standard Model. As ALPs couple to on‐shell fermions proportionally to their masses, processes involving both types of particles may give rise, for TeV HNLs, to relevant phenomenology at colliders.

Who's Afraid of the Supersymmetric Dark? The Standard Model vs Low‐Energy Supergravity
Fortschritte der Physik, Volume 70, Issue 7-8, August 2022., 2022 Abstract Use of supergravity equations in astronomy and late‐universe cosmology is often criticized on three grounds: (i) phenomenological success usually depends on the supergravity form for the scalar potential applying at the relevant energies; (ii$ii$) the low‐energy scalar potential is extremely sensitive to quantum effects involving very massive ...

Axion–Sterile Neutrino Dark Matter [PDF]
Universe, 2021 Extending the standard model with three right-handed neutrinos and a simple QCD axion sector can account for neutrino oscillations, dark matter and baryon asymmetry; at the same time, it solves the strong CP problem, stabilizes the electroweak vacuum and can implement critical Higgs inflation (satisfying all current observational bounds).

A novel solution for controlling hardware components of accelerators and beamlines
Journal of Synchrotron Radiation, Volume 29, Issue 3, Page 644-653, May 2022., 2022 A novel approach to the remote‐control system for the compact multi‐crystal energy‐dispersive spectrometer for X‐ray emission spectroscopy applications is described.A novel approach to the remote‐control system for the compact multi‐crystal energy‐dispersive spectrometer for X‐ray emission spectroscopy (XES) applications has been developed.

Neutrinoastronomie in der Antarktis
Physik in unserer Zeit, Volume 52, Issue 2, Page 66-72, March 2021., 2021 Vor zehn Jahren ging in der Antarktis das Neutrinoteleskop IceCube in Betrieb. Bis heute wurden damit über hundert Neutrinos von kosmischen „Beschleunigern” nachgewiesen. In einem Fall ließ sich eine aktive Galaxie als mögliche Quelle identifizieren. Zusammenfassung Fast hundert Jahre nach der Vorhersage von Neutrinos sind wir heute in der Lage, diese ...

Atomic ionization by sterile-to-active neutrino conversion and constraints on dark matter sterile neutrinos with germanium detectors [PDF]
, 2016 The transition magnetic moment of a sterile-to-active neutrino conversion gives rise to not only radiative decay of a sterile neutrino, but also its non-standard interaction (NSI) with matter.

Sterile neutrino as a bulk neutrino [PDF]
Nuclear Physics B, 2000 If light sterile neutrinos are needed to understand the neutrino puzzles, as is currently indicated, a major theoretical challenge is to understand why its mass is so small. It is a more serious problem than understanding the small mass of the familiar neutrinos.

Can Neutrino Self-interactions Save Sterile Neutrino Dark Matter?
The Astrophysical Journal Letters, 2023 Sterile neutrinos only interact with the standard model through the neutrino sector, and thus represent a simple dark matter (DM) candidate with many potential astrophysical and cosmological signatures.
