Impact of eV-mass sterile neutrinos on neutrino-driven supernova outflows
, 2012 Motivated by recent hints for sterile neutrinos from the reactor anomaly, we study active-sterile conversions in a three-flavor scenario (2 active + 1 sterile families) for three different representative times during the neutrino-cooling evolution of the

Heavy neutrino production via $Z'$ at the lifetime frontier [PDF]
, 2019 We investigate the pair production of right-handed neutrinos from the decay of an additional neutral $Z^{\prime}$ boson in the gauged $B-L$ model. Taking into account current constraints on the $Z^{\prime}$ mass and the associated gauge coupling $g_{1}^{\

Investigating the Sterile Neutrino Parameters with QLC in 3 + 1 Scenario
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 In the scenario with four generation quarks and leptons and using a 3 + 1 neutrino model having one sterile and the three standard active neutrinos with a 4 × 4 unitary transformation matrix, UPMNS4, we perform a model‐based analysis using the latest global data and determine bounds on the sterile neutrino parameters i.e., the neutrino mixing angles ...

Emergent neutrinos from heavy messengers
Journal of High Energy Physics, 2022 Fermionic bound states (mesinos) of messengers can play the role of right-handed neutrinos and due to their heavy masses they can realize the seesaw mechanism providing light and heavy sterile neutrinos.

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 Inspired by the experimental anomalies in neutrino physics and recent oscillation data from short baseline and another neutrino experiment, the realization of one extra neutrino flavor seems to be favoring. This extra flavor may change the observable, |mββ|, of current data taking and next‐generation (ββ) 0ν‐decay experiments aim to probe and possibly ...

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).

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.
