Feasibility Study on the Discrimination of Fluor Concentration in the Liquid Scintillator Using PMT Waveform and Short-Pass Filter

open access: yesSensors, 2023
Neutrinos are difficult to detect because they weakly interact with matter, making their properties least known. The response of the neutrino detector depends on the optical properties of the liquid scintillator (LS).

Neutrino mixing and neutrino telescopes [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2007
Measuring flux ratios of ultra-high energy neutrinos is an alternative method to determine the neutrino mixing angles and the CP phase delta. We conduct a systematic analysis of the neutrino mixing probabilities and of various flux ratios measurable at neutrino telescopes.

Sterile neutrinos in astrophysical neutrino flavor [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
Current global constraints in neutrino mixing parameters translate to lax PMNS unitarity relations. In this work, we explore the lack of non-unitarity in the neutrino mixing matrix via the astrophysical neutrino flavor content in both standard paradigms, as well as those involving sterile neutrinos.

Determining the Neutrino Mass Hierarchy with Atmospheric Neutrinos [PDF]

open access: yes, 2005
The possibility to determine the type of neutrino mass hierarchy by studying atmospheric neutrino oscillations with a detector capable to distinguish between neutrino and antineutrino events, such as magnetized iron calorimeters, is considered.

Relic Neutrino Absorption Spectroscopy [PDF]

open access: yes, 2004
Resonant annihilation of extremely high-energy cosmic neutrinos on big-bang relic anti-neutrinos (and vice versa) into Z-bosons leads to sizable absorption dips in the neutrino flux to be observed at Earth.

Neutrino flavor relaxation or neutrino oscillations? [PDF]

open access: yesJournal of Experimental and Theoretical Physics Letters, 2004
We propose the new mechanism of neutrino flavour relaxation to explain the experimentally observed changes of initial neutrino flavour fluxes. The test of neutrino relaxation hypothesis is presented, using the data of modern reactor, solar and accelerator experiments. The final choice between the standard neutrino oscillations and the proposed neutrino
