Abstract Neutrino oscillation is an important physical phenomenon in elementary particle physics, and its nonclassical features can be revealed by the Leggett–Garg inequality. It shows that quantum coherence sustained over astrophysical length scales. In this work, we investigate measure of quantumness experimentally observed neutrino oscillations via nonlocal advantage (NAQC), steering, Bell nonlocality. From various sources, ensembles reactor accelerator neutrinos are analyzed at distinct...
Neutrino oscillation represents an intriguing physical phenomenon where the quantumness can be maintained and detected over a long distance. Previously, nonclassical character of neutrino was tested with Leggett-Garg inequality, clear violation classical bound observed [J. A. Formaggio et al., Phys. Rev. Lett. 117, 050402 (2016)]. However, there are several limitations in testing oscillations inequality. In particular, degree inequality cannot taken as ``measure quantumness.'' Here, we focus...
A bstract We present results of a combined analysis in neutrino oscillations without unitarity assumption the 3 ν mixing picture. Constraints on matrix elements are based recent data from reactor, solar and long-baseline accelerator oscillation experiments. The current consistent with standard scheme. precision different can be as good few percent at σ CL, is mainly limited by experimental statistical uncertainty. e related most precisely measured among all sectors uncertainties < 20%....

We obtain an analytic equation that predict position dip. also place constraints on parameter space neutrinos using latest Borexino KamLAND find high data at are sensitive different regions space. case with...
Abstract The existence of light sterile neutrinos is a long-standing question in particle physics. Several experimental “anomalies” might be explained by introducing eV mass scaled neutrinos. Many experiments are actively searching for such through neutrino oscillation. For long baseline experiments, the matter effect should treated carefully precise calculation oscillation probabilities. However, this usually time-consuming or analytically complex. In manuscript, we adopt Jacobi-like method...
A bstract The light sterile neutrino, if it exists, will give additional contribution to matter effect when active neutrinos propagate through terrestrial matter. In the simplest 3+1 scheme, three more rotation angles and two CP-violating phases in lepton mixing matrix make interaction complicated formally. this work, exact analytical expressions for neutrino oscillation probabilities matter, including contribution, are derived. It is pointed out that set of formulas contain information both...
The existence of sterile neutrino is an open question in physics up to now. method oscillometry provides a powerful tool test the common 3+1 hypothesis, i.e. three active flavors and one falvor. There are several antineutrino sources can be used for this method. One them well known isotope chain $^{144}{\rm Ce}-$$^{144}{\rm Pr}$ with initial activity around 50-100 kCi. It has compact size might installed either outside or inside detector. Another short-lived $\rm^8Li$, which produced nuclear...

Neutrino-antineutrino conversion is an important new physics process. The observation of this phenomenon could indicate total lepton number violation and potential CPT-violation. Searching for the appearance electron antineutrinos from solar neutrinos B8 decay allows us to hunt rare process, although it can also be explained by other mechanisms or hypotheses. This analysis examines capabilities observing neutrino-antineutrino transition unoscillated using different liquid scintillator...
Neutrino magnetic moment ($\nu$MM) is an important property of massive neutrinos. The recent anomalous excess at few keV electronic recoils observed by the Xenon1T collaboration might indicate a $\sim 2.2\times10^{-11} \mu_B$ effective neutrino ($\mu_\nu^{eff}$) from solar Therefore, it essential to carry out $\nu$MM searches different experiment confirm or exclude such hypothesis. We study feasibility doing measurement with 4 kton active mass Jinping using electron recoil data both natural...
