Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Long‐Baseline Oscillation Experiments as a Tool to Probe High Energy Flavor Symmetry Models
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We review the current status of neutrino oscillation experiments, mainly focusing on T2(H)K, NOνA, and DUNE. Their capability to probe high energy physics is found in the precision measurement of the CP phase and θ23. In general, neutrino mass models predict correlations among the mixing angles that can be used to scan and shrink their parameter space.

Heavy neutral leptons — Advancing into the PeV domain
Journal of High Energy Physics, 2023 Heavy neutral leptons (HNLs) are hypothetical particles able to explain neutrino oscillations and provide a mechanism for generating the baryon asymmetry of the Universe.

Searching for the Minimal Seesaw Models at the LHC and Beyond
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 The existence of the tiny neutrino mass and the flavor mixing can be naturally explained by type I Seesaw model which is probably the simplest extension of the Standard Model (SM) using Majorana type SM gauge singlet heavy Right Handed Neutrinos (RHNs).

Singlet Fermion Assisted Dominant Seesaw with Lepton Flavor and Number Violations and Leptogenesis
Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017 Embedding type I seesaw in GUTs, left‐right gauge theories, or even in extensions of the SM requires large right‐handed neutrino masses making the neutrino mass generation mechanism inaccessible for direct experimental tests. This has been circumvented by introducing additional textures or high degree of fine‐tuning in the Dirac neutrino or right ...

The geometric νSMEFT: operators and connections
Journal of High Energy Physics, 2023 We write down a geometric realization of the Standard Model Effective Field Theory (SMEFT) extended by n f flavours of light sterile neutrinos, a so-called geoνSMEFT.

Cosmological and astrophysical bounds on a heavy sterile neutrino and the KARMEN anomaly [PDF]
Nuclear Physics B, 2000 Constraints on the lifetime of the heavy sterile neutrino, that was proposed as a possible interpretation of the KARMEN anomaly, are derived from primordial nucleosynthesis and SN 1987A. Together with the recent experimental bounds on the nu_s lifetime, SN 1987A completely excludes this interpretation.

Impact of unitarity violation on sensitivity of the leptonic CP phase at Hyper-Kamiokande and DUNE
Journal of High Energy PhysicsWe study the impact of unitarity violation on the sensitivity of the leptonic CP phase, δ CP, considering the next generation of long-baseline neutrino experiments, Hyper-Kamiokande and DUNE.
