Limits on Active to Sterile Neutrino Oscillations from Disappearance Searches in the MINOS, Daya Bay, and Bugey-3 Experiments. [PDF]

open access: yesPhysical Review Letters, 2016
Searches for a light sterile neutrino have been performed independently by the MINOS and the Daya Bay experiments using the muon (anti)neutrino and electron antineutrino disappearance channels, respectively.

Limits on Dark Photons, Scalars, and Axion‐Electromagnetodynamics with the ORGAN Experiment

open access: yesAnnalen 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.

Collective neutrino oscillations and neutrino wave packets [PDF]

open access: yes, 2017
Effects of decoherence by wave packet separation on collective neutrino oscillations in dense neutrino gases are considered. We estimate the length of the wave packets of neutrinos produced in core collapse supernovae and the expected neutrino coherence ...

New Ambiguity in Probing CP Violation in Neutrino Oscillations. [PDF]

open access: yesPhysical Review Letters, 2016
If neutrinos get mass via the seesaw mechanism the mixing matrix describing neutrino oscillations can be effectively nonunitary. We show that in this case the neutrino appearance probabilities involve a new CP phase ϕ associated with nonunitarity.

Hermitian Matrix Diagonalization and Its Symmetry Properties

open access: yesAdvances 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 ...

Quantum walks as simulators of neutrino oscillations in a vacuum and matter [PDF]

open access: yes, 2016
We analyze the simulation of Dirac neutrino oscillations using quantum walks, both in a vacuum and in matter. We show that this simulation, in the continuum limit, reproduces a set of coupled Dirac equations that describe neutrino flavor oscillations ...

Statistical Issues on the Neutrino Mass Hierarchy with Δχ2

open access: yesAdvances 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.

Entanglement and collective flavor oscillations in a dense neutrino gas

open access: yesPhysical Review D, 2019
We investigate the importance of going beyond the mean-field approximation in the dynamics of collective neutrino oscillations. To expand our understanding of the coherent neutrino oscillation problem, we apply concepts from many-body physics and quantum

Higgs Information and NMSSM at the Large Hadron Collider

open access: yesAdvances in High Energy Physics, Volume 2024, Issue 1, 2024.
Information theory has proven to be a worthwhile tool for investigating the implications of the Higgs sector in the Next‐to‐Minimal Supersymmetric Standard Model (NMSSM) using Higgs information at the Large Hadron Collider (LHC) assessed through the entropy constructed by means of the branching ratios of decay channels of the Higgs boson.

Oscillations of Mössbauer neutrinos

open access: yesJournal 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 ...
