Limits on Dark Photons, Scalars, and Axion‐Electromagnetodynamics with the ORGAN Experiment
Annalen der Physik, Volume 536, Issue 1, January 2024.The nature of dark matter is one of the biggest mysteries in the Universe. ORGAN is an experiment which seeks to understand dark matter by figuring out what it is made of. In this article, the current sensitivity of ORGAN to various promising dark matter candidates is presented, and the future sensitivity is projected.

Oscillations of Mössbauer neutrinos
Journal of High Energy Physics, 2008 We calculate the probability of recoilless emission and detection of neutrinos (Mossbauer effect with neutrinos) taking into account the boundedness of the parent and daughter nuclei in the neutrino source and detector as well as the leptonic mixing. We show that, in spite of their near monochromaticity, the recoillessly emitted and captured neutrinos ...

Hermitian Matrix Diagonalization and Its Symmetry Properties
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.A Hermitian matrix can be parametrized by a set consisting of its determinant and the eigenvalues of its submatrices. We established a group of equations which connect these variables with the mixing parameters of diagonalization. These equations are simple in structure and manifestly invariant in form under the symmetry operations of dilatation ...

Neutrino oscillations and scattering theory
Journal of High Energy PhysicsWe derive the neutrino oscillation probability in vacuum using scattering theory methods developed earlier in the context of collider physics [1–3]. It is computed from Feynman diagrams that combine neutrino production and detection processes into a ...

Neutrino masses and oscillations
, 2005 I summarize the status of three--neutrino oscillations that follow from combining the relevant world's data. The discussion includes the small parameters Delta_m-sol/Delta_m-atm and \sin^2\theta_{13}, which characterize the strength of CP violation in ...

Phenomenology of neutrino oscillations [PDF]
Pramana, 2000 The phenomenology of solar, atmospheric, supernova and laboratory neutrino oscillations is described. Analytical formulae for matter effects are reviewed. The results from oscillations are confronted with neutrinoless double beta decay.

Statistical Issues on the Neutrino Mass Hierarchy with Δχ2
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.The neutrino mass hierarchy determination (ν MHD) is one of the main goals of the major current and future neutrino experiments. The statistical analysis usually proceeds from a standard method, a single‐dimensional estimator (1D − Δχ2) that shows some drawbacks and concerns, together with a debatable strategy.

Quantification of quantumness in neutrino oscillations
European Physical Journal C: Particles and Fields, 2020 Neutrino oscillation is an important physical phenomenon in elementary particle physics, and its nonclassical features can be revealed by the Leggett–Garg inequality.

Impact of right-handed interactions on the propagation of Dirac and Majorana neutrinos in matter
, 2007 Dirac and Majorana neutrinos can be distinguished in relativistic neutrino oscillations if new right-handed interactions exist, due to their different propagation in matter. We review how these new interactions affect neutrino oscillation experiments and

Measurement of Neutrino Oscillations with Neutrino Telescopes [PDF]
Advances in High Energy Physics, 2013 IceCube and ANTARES are the world-largest neutrino telescopes. They are successfully taking data, producing a wealth of scientific results. Whereas their main goal is the detection of cosmic neutrinos with energies in the TeV-PeV range, both have demonstrated their capability to measure neutrino oscillations by studying atmospheric neutrinos with ...
