Mixed states for neutral current neutrino oscillation

Nuclear Physics B, 2023
The theory of neutrino oscillation predicts that if both neutrino and antineutrino coming from Z0 decay are detected, one can observe an oscillation pattern between the corresponding detectors.

Oscillation effects on high-energy neutrino fluxes from astrophysical hidden sources [PDF]

, 2006
High-energy neutrinos are expected to be produced in a vareity of astrophysical sources as well as in optically thick hidden sources. We explore the matter-induced oscillation effects on emitted neutrino fluxes of three different flavors from the latter ...

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.

Higgs Information and NMSSM at the Large Hadron Collider

Advances 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.

Neutrino Oscillation Effects on the Luminosity of Neutrino-dominated Accretion Flows around Black Holes

The Astrophysical Journal
A stellar-mass black hole surrounded by the neutrino-dominated accretion flow (NDAF) has been proposed as the central engine of gamma-ray bursts. In this work, we investigate the neutrino/antineutrino luminosity and annihilation luminosity from the NDAF ...

Progress in neutrino oscillation searches and their implications

, 2003
Neutrino Oscillation, in which a given flavour of neutrino transforms into another is a powerful tool for probing small neutrino masses. The intrinsic neutrino properties involved are neutrino mass squared difference $\Delta m^2$ and the mixing angle in ...

Deviations From μ‐τ Symmetry Using Δ(27) Group on Neutrino Masses and Mixings

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
The implication of the neutrino mass model based on Δ(27) discrete flavor symmetry, on parameters of neutrino oscillations, CP violation, and effective neutrino masses is studied using the Type I seesaw mechanism. The standard model particle content is extended by adding two additional Higgs doublets, three right‐handed neutrinos, and two scalar ...

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 ...

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 ...

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.
