The upgraded T2K off-axis near detector (ND280) will allow to improve constraints on the systematic uncertainties that are currently limiting the neutrino oscillation sensitivity. A better understanding of the flux and neutrino-nucleus interactions models are indeed essential to determine the neutrino mass hierarchy and the extent of CP-violation generated in the lepton sector. In particular,...
The production process of tau neutrinos is, up-to-date, largely unknown compared with other neutrino flavors. The NA65 (DsTau) experiment is an approved CERN experiment with the scope to investigate the tau neutrino production using an emulsion cloud chamber (ECC).
The main production process of tau neutrinos is the sequential decay of Ds mesons produced by the reaction of the high-energy...
The SHiP Collaboration has proposed a general-purpose experimental facility operating in beam dump mode at the CERN SPS accelerator with the aim of searching for light, long-lived exotic particles of Hidden Sector models.
The SHiP experiment incorporates a muon shield based on magnetic sweeping and two complementary apparatuses. The detector immediately downstream of the muon shield is...
The discovery of cosmic neutrinos with IceCube has opened a new window on the universe. In 2013 the IceCube Collaboration has discovered a diffuse flux of cosmic neutrinos, and in 2017 evidence for a possible first point source of high-energy neutrinos. At the same time it is clear, that a global effort is necessary to resolve the high-energy neutrino sky in detail. IceCube is flanked by...
The iron-scintillation detector LVD is designed to detect various types of neutrinos from collapsing stars in our Galaxy and in Magellanic Clouds. The report will present the results for 28 years of the experiment's existence. New limit has been set on the frequency of supernova detection in our Galaxy. The results of the correlation analysis between detectors LVD and BUST are presented. The...
We have considered a model, where masses and a mixing pattern for neutrinos
are governed by six Higgs triplets and $A_4$ symmetry. In this model we have applied a certain diagonalisation procedure through which we have shown that neutrino
masses can have both normal or inverted hierarchy. We have also shown that current
neutrino oscillation data can be explained in this model. (arxiv=2003.09809)
Borexino collaboration announced at Neutrino 2020 the observation of CNO neutrinos from the Sun. The value of the flux is appeared higher than predicted by the Standard Solar Model. This could be interpreted as observation of an additional neutrino source in the same energy region. One of possible sources is $^{40}$K antineutrino flux. The value of additional source can claim the potassium...
In sterile neutrino (3+1) parameterisation, we observe that sterile phases ($\delta_{14},\delta_{24}$) are always together in oscillation probability, even when the MSW effect is considered. We see that the difference between the sterile phases has a more dominating effect over event rates compared to small variations due to changes in individual values. In this work, we show the value of...
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for neutrinoless double-beta (0νββ) decay that has been able to reach the one-ton scale. The detector, located at the Laboratori Nazionali del Gran Sasso in Italy, consists of an array of 988 TeO2 crystals arranged in a compact cylindrical structure of 19 towers. Following the completion...
The CUPID-Mo experiment is a demonstrator for a next-generation CUPID experiment. The first results of the CUPID-Mo experiment to study neutrinoless double beta decay of 100Mo are presented. The measurements are carried out in the the Laboratoire Souterrain de Modane (France) at a depth of 4800 m w.e. using low-temperature scintillating bolometers based on Li2MoO4 crystals. The installation...
The LEGEND Collaboration aims to combine the successes of the GERDA Experiment and the {\sc Majorana Demonstrator} with newly-developed technologies in a ton-scale, germanium-based experiment with discovery potential spanning the inverted neutrino mass-hierarchy regime. The LEGEND Collaboration has established a phased deployment scheme: an initial 200-kg array (LEGEND-200), deployed in the...
Two and three flavor oscillating neutrinos are shown to exhibit the properties bipartite and tripartite quantum entanglement respectively. The two and three flavour neutrinos are mapped to qubit states used in quantum information theory. Such quantum bits of the neutrino state can be encoded on a IBMQ computer using quantum computing as a tool. We construct a 3x3 PMNS...
While oscillations of solar neutrinos are usually studied using the single-particle quantum-mechanical approach, flavor conversions of supernovae neutrinos are typically analyzed using the kinetic equation for the matrix of densities due to the necessity of including also the scattering processes. Using the Wigner formulation of quantum mechanics we show the equivalence of the...
