Heavy neutral leptons at muon colliders

open access: yesJournal of High Energy Physics, 2023
The future high-energy muon colliders, featuring both high energy and low background, could play a critical role in our searches for new physics. The smallness of neutrino mass is a puzzle of particle physics.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte 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

open access: yesAdvances 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.

Searching for the Minimal Seesaw Models at the LHC and Beyond

open access: yesAdvances 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

open access: yesAdvances 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 ...

Naturally light sterile neutrinos

open access: yes, 1999
A simple model to accommodate light sterile neutrinos naturally with large mixing with the usual neutrinos has been proposed. The standard model gauge group is extended to include an SU(2)S gauge symmetry. Heavy triplet Higgs scalars give small masses to

Impact of unitarity violation on sensitivity of the leptonic CP phase at Hyper-Kamiokande and DUNE

open access: yesJournal of High Energy Physics
We 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.

Heavy neutral leptons — Advancing into the PeV domain

open access: yesJournal 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.

Shadow dark matter, sterile neutrinos and neutrino events at IceCube

open access: yes, 2015
The excess of high energy neutrinos observed by the Ice Cube collaboration might originate from baryon number violating decays of heavy shadow baryons from dark mirror sector which produce shadow neutrinos.

The geometric νSMEFT: operators and connections

open access: yesJournal 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.
