We revisit a method for determining the neutrino mass ordering by using precision measurements of the atmospheric $\Delta m^2$'s in both electron neutrino and muon neutrino disappearance channels, proposed by the authors in 2005~\cite{Nunokawa:2005nx}. The mass ordering is a very important outstanding question for our understanding of the elusive neutrino and determination of the mass...
NOvA is a long-baseline neutrino oscillation experiment consisting of two functionally identical tracking calorimeters, and a beam of neutrinos. The near detector is located at Fermilab, where it measures neutrinos coming from the 1 MW-capable NuMI beam. The beam can be run in neutrino or antineutrino mode, to produce a highly pure flux of muon (anti)neutrinos. The neutrinos then travel 810km...
T2K is a long-baseline experiment for the measurement of neutrino and antineutrino oscillations. (Anti)neutrinos are produced by the J-PARC accelerator and measured at the ND280 near detector, and then at the Super-Kamiokande far-detector, in Kamioka. The most recent results of neutrino oscillations will be presented, featuring world-leading sensitivities on the search of Charge-Parity...
IceCube DeepCore is a subarray of the IceCube Neutrino Observatory that gives the detector sensitivity to GeV-scale atmospheric neutrinos by virtue of the closer spacing of its digital optical modules. With ten years of observation of GeV neutrinos over a range of long baselines, IceCube has placed competitive constraints on the atmospheric oscillation parameters $\sin^2(\theta_{23})$ and...
Tokai to Kamioka (T2K) is a long-baseline neutrino oscillation experiment that measures oscillation parameters related to both $\nu_\mu(\bar{\nu}_\mu)$ disappearance and $\nu_e(\bar{\nu}_e)$ appearance in a $\nu_\mu(\bar{\nu}_\mu)$ beam. T2K uses Super-Kamiokande (SK) as its far detector, and SK detector systematic errors are currently among the leading sources of systematic uncertainty in the...
The next generation of neutrino oscillation experiments, JUNO, DUNE, and HK, are under construction now and will collect data over the next decade and beyond. As there are no approved plans to follow up this program with more advanced neutrino oscillation experiments, we consider here one option that had gained considerable interest more than a decade ago: a neutrino factory. Such an...
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kton liquid scintillator detector currently under construction 700 m underground in southern China. The detector is located 53 km from the Taishan and Yangjiang nuclear power plants and will simultaneously probe solar ($\Delta m^2_{21}$) and atmospheric ($\Delta m^2_{31}$) oscillations using reactor antineutrinos. The primary goals...
The Hyper-Kamiokande (Hyper-K) is the third generation of underground water Cherenkov detectors in Japan. It will serve twofold: as the far detector for a long-baseline neutrino oscillation experiment for the upgraded, to 1.3 MW power, J-PARC muon neutrino/antineutrino beam and as a detector capable of observing proton decays, atmospheric neutrinos, and neutrinos from astronomical sources. It...
The Deep Underground Neutrino Experiment (DUNE) is a next generation, long-baseline neutrino oscillation experiment which will utilize a high-intensity $\nu_{\mu}$ and $\bar{\nu}_{\mu}$ beam, sampled twice, over a 1285 km baseline, to make discovery-level measurements of neutrino mixing. The unoscillated neutrino flux, which peaks at about 2.5 GeV, will be constrained with the near detector...
The IceCube Upgrade will be an extension of the IceCube Neutrino Observatory which consists of the addition of 7 more densely instrumented strings placed within the IceCube DeepCore volume to enhance performance in the GeV energy range. The additional strings will feature new types of instruments and optical modules, each containing multiple photomultiplier tubes (PMTs), which will improve the...
T2K (Tokai to Kamioka) is a Japan-based long-baseline neutrino oscillation experiment designed to measure (anti)neutrino flavor oscillations. A muon (anti-)neutrino beam peaked around 0.6 GeV is produced in Tokai and directed toward the water Cherenkov far detector Super-Kamiokande (SK) located at 295 km. The ND280 is used to characterise the neutrino beam before the oscillation, and its data...
For the operation of precision neutrino experiments, the understanding of neutrino interactions with matter are preconditioned requirements of all detections and measurements of neutrinos. The largest uncertainties in estimating neutrino-nucleus interaction cross sections arise in the incomplete understanding of nuclear effects. In the study of neutrino oscillations and nuclear scattering...
The Short-Baseline Near Detector (SBND) is a crucial component of the Short-Baseline Neutrino (SBN) Program, situated 110 meters from the Booster Neutrino Beam (BNB) target. This 112-ton Liquid Argon Time Projection Chamber (LArTPC) Near Detector is optimally positioned to investigate the potential existence of an additional flavor of neutrino through neutrino oscillation. Due to its proximity...
NOvA is a long-baseline neutrino oscillation experiment that looks for the disappearance of muon (anti)neutrinos and the appearance of electron (anti)neutrinos in a beam of muon (anti)neutrinos. In addition to using Bayesian methods, NOvA employs a classical maximum-likelihood estimation to measure neutrino mixing parameters, determine the neutrino mass ordering, and search for CP violation in...
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kiloton liquid scintillator detector, currently under construction in southern China. JUNO aims to reach an unprecedented energy resolution of 3% at 1 MeV to achieve its primary physics goal of determining the neutrino mass ordering, by resolving fine structure due to flavor oscillations in the antineutrino energy spectrum from...
Atmospheric neutrinos, through their weak interactions, serve as an independent tool for exploring the internal structure of Earth. This information is complementary to that obtained from seismic and gravitational measurements. The Earth matter effects depend upon the energy of neutrinos and the electron density distribution they encounter during their journey through Earth, and hence, can be...
The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino oscillation experiment designed to make precision measurements in the world's most powerful neutrino beam. Neutrinos are measured at two detector facilities: a near detector located at Fermilab close to where the beam is produced and a far detector at SURF. A key component of the near detector is the...
A high-precision measurement of $\Delta m^2_{31}$ and $\theta_{23}$ is inevitable to estimate the Earth's matter effect in long-baseline experiments which in turn plays an important role in addressing the issue of neutrino mass ordering and to measure the value of CP phase in $3\nu$ framework. After reviewing the results from the current experiments and discussing the near-future sensitivities...
After the landmark discovery of non-zero $\theta_{13}$ by the modern reactor experiments, unprecedented precision on neutrino mass-mixing parameters has been achieved over the past decade. This has set the stage for the discovery of leptonic CP violation (LCPV) at high confidence level in the next-generation long-baseline neutrino oscillation experiments. In this work, we explore in detail...
