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 ...

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.

Warm dark matter sterile neutrinos in electron capture and beta decay spectra [PDF]
, 2016 We briefly review the motivation to search for sterile neutrinos in the keV mass scale, as dark matter candidates, and the prospects to find them in beta decay or electron capture spectra, with a global perspective.

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.

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.

Higgs production from sterile neutrinos at future lepton colliders [PDF]
, 2015 In scenarios with sterile (right-handed) neutrinos that are subject to an approximate "lepton-number-like" symmetry, the heavy neutrinos (i.e. the mass eigenstates) can have masses around the electroweak scale and couple to the Higgs boson with, in ...

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

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 ...

Nearly degenerate heavy sterile neutrinos in cascade decay: mixing and oscillations [PDF]
, 2003 Some extensions beyond the Standard Model propose the existence of nearly degenerate heavy sterile neutrinos. If kinematically allowed these can be resonantly produced and decay in a cascade to common final states.

Improving heavy Dirac neutrino prospects at future hadron colliders using machine learning
Journal of High Energy Physics, 2022 In this work, by using the machine learning methods, we study the sensitivities of heavy pseudo-Dirac neutrino N in the inverse seesaw at the high-energy hadron colliders.
