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.

Sterile neutrinos and right-handed currents in KATRIN [PDF]

, 2014
Kurie-plot experiments allow for neutrino-mass measurements based on kinematics in an almost model-independent manner. A future tritium-based KATRIN-like experiment can be sensitive to light sterile neutrinos with masses below 18 keV, which are among the

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).

Low-scale leptogenesis with three heavy neutrinos

, 2018
Leptogenesis induced by the oscillations of GeV-scale neutrinos provides a minimal and testable explanation of the baryon asymmetry of the Universe. In this work we extend previous studies invoking only two heavy neutrinos to the case of three heavy ...

Low-Scale See-Saw Mechanisms for Light Neutrinos [PDF]

, 2000
Alternatives to the see-saw mechanism are explored in supersymmetric models with three right-handed or sterile neutrinos. Tree-level Yukawa couplings can be drastically suppressed in a natural way to give sub-eV Dirac neutrino masses.

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.

QCD corrections to charged-current decays with Heavy Sterile Neutrinos in initial or final state and their impact on $τ$ decays

Searches for a Heavy Sterile Neutrino $N$ profit from precise predictions of inclusive decay rates, entering predictions for branching fractions and lifetime. Once decay channels into semi-hadronic final states are open, a reliable calculation of inclusive decay rates is only possible if $N$ is heavy enough to permit a perturbative calculation.
