Sensitivity of the FACET experiment to Heavy Neutral Leptons and Dark Scalars
Journal of High Energy Physics, 2023 We analyze the potential of the recently proposed experiment FACET (Forward-Aperture CMS ExTension) to search for new physics. As an example, we consider the models of Higgs-like scalars with cubic and quartic interactions and Heavy Neutral Leptons.

Signatures of Dirac and Majorana Sterile Neutrinos in Trilepton Events at the LHC [PDF]
, 2017 Heavy sterile neutrinos with masses below $M_W$ can induce trilepton events at the 14 TeV LHC through purely leptonic $W$ decays of $W^\pm \to e^\pm e^\pm \mu^\mp \nu$ and $\mu^\pm \mu^\pm e^\mp \nu$ where the heavy neutrino will be in an intermediate ...

Long-lived heavy neutral leptons with a displaced shower signature at CMS
Journal of High Energy Physics, 2023 We study the LHC discovery potential in the search for heavy neutral leptons (HNL) with a new signature: a displaced shower in the CMS muon detector, giving rise to a large cluster of hits forming a displaced shower. A new Delphes module is used to model

Nuclear Effects and CP Sensitivity at DUNE
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 The precise measurement of neutrino‐oscillation parameters is one of the highest priorities in neutrino‐oscillation physics. To achieve the desired precision, it is necessary to reduce the systematic uncertainties related to neutrino energy reconstruction.

Journal of High Energy Physics, 2023 A muon collider could produce the heavier Standard Model particles with a boost, for example in resonant processes such as μ − μ + → h or μ − μ → Z. We propose machine configurations that produce the boost (asymmetric beam energies, tilted beams) and ...

Neutrino Masses in the Effective Rank-5 Subgroups of E_6 I: Non-supersymmetric Case [PDF]
, 2005 The neutral fermion sectors of E_6-inspired low energy models, in particular the Alternative Left-Right and Inert models, are considered in detail within the non-supersymmetric scenario.

DUNE Prospect for Leptophobic Dark Matter
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 Highly energetic proton/electron beam fixed‐target experiments extend an opportunity to probe the sub‐GeV dark matter and associated interactions. In this work, we have explored the sensitivity of DUNE (Deep Underground Neutrino Experiment) for sub‐GeV leptophobic dark matter, i.e., this dark matter barely couples with the leptons.

Constraints on NJL four-fermion effective interactions from neutrinoless double beta decay
Journal of High Energy Physics, 2023 We study the contribution of a heavy right-handed Majorana neutrino to neutrinoless double beta decay (0νββ) via four-fermion effective interactions of Nambu-Jona-Lasinio (NJL) type.

Matter effects and CP violating neutrino oscillations with non-decoupling heavy neutrinos [PDF]
, 2002 The evolution equation for active and sterile neutrinos propagating in general anisotropic or polarized background environment is found and solved for a special case when heavy neutrinos do not decouple, resulting in non-unitary mixing among light ...
