Investigating Sterile Neutrino Flux in the Solar Neutrino Data
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 There are compelling evidences for the existence of a fourth degree of freedom of neutrinos, i.e., sterile neutrino. In the recent studies the role of sterile component of neutrinos has been found to be crucial, not only in particle physics, but also in astrophysics and cosmology.

Neutrino seesaw models at one-loop matching: discrimination by effective operators
Journal of High Energy Physics, 2022 Using the functional method, one-loop matching of the type-I, -II and -III see-saw models are investigated and the results are presented in both the Green’s and the Warsaw bases. Although these models generate the same dimension-5 Weinberg operator, they

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 Very recently novel implementation of type‐II seesaw mechanism for neutrino mass has been proposed in SU(5) grand unified theory with a number of desirable new physical phenomena beyond the standard model. Introducing heavy right‐handed neutrinos and extra fermion singlets, in this work we show how the type‐I seesaw cancellation mechanism works in this

HNL mass degeneracy: implications for low-scale seesaws, LNV at colliders and leptogenesis
Journal of High Energy Physics, 2023 Low-scale seesaw variants protected by lepton number symmetry provide a natural explanation of the smallness of neutrino masses but, unlike their higher-scale counterparts, with potentially testable phenomenology.

Heavy neutral leptons at muon colliders
Journal 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.

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 ...

Prospects for testing electroweak scale sterile neutrinos at future colliders [PDF]
, 2018 The extension of the Standard Model of particle physics by sterile neutrinos can naturally explain the smallness of neutrino masses as observed by neutrino oscillation and nuclear beta decay experiments.

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 ...

Self-interacting sterile neutrino dark matter: The heavy-mediator case [PDF]
Physical Review D, 2019 For active-sterile mixing to be responsible for the full relic abundance of dark matter additional new physics is needed beyond the keV-scale sterile neutrino itself. The extra ingredient we consider here is the presence of self-interactions among the sterile neutrinos.

Annalen der Physik, Volume 537, Issue 12, December 2025.A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.
