We will describe the opportunities offered by long baseline oscillation experiments and highlight the role played by the near detector as well as the far detectors. This discussion would mainly revolve around the upcoming Deep Underground Neutrino Experiment (DUNE). DUNE will detect neutrinos generated in the LBNF beamline at Fermilab, using a Near Detector (ND) situated near the beam target...

The latest data of the two long-baseline accelerator experiments NOฮฝA and T2K, interpreted in the standard 3-flavor scenario, display a discrepancy. A mismatch in the determination of the standard CP-phase $\delta_{\rm CP}$ extracted by the two experiments is evident in the normal neutrino mass ordering. While NOฮฝA prefers values close to $\delta_{\rm CP} \sim 0.8\pi$, T2K identifies values of...

NOvA is a long-baseline beam neutrino experiment. It uses the 700 kW NuMI beam at Fermilab to send muon neutrinos (or muon antineutrinos) to two functionally identical detectors, located 14.6 mrad off the beam axis. The Near Detector (ND) is located at Fermilab, 1 km from the neutrino source and the 14 kton Far Detector (FD) is located 810 km away in Ash River, Minnesota. Both the detectors...

Dark matter (DM), if captured in considerable amount at the Solar core may undergo the process of self-annihilation producing standard model particles such as neutrinos, charged leptons, or gamma as the end product. Neutrinos, thus produced in the Solar core from DM annihilation may be detected at a terrestrial neutrino detector. KM3NeT is an under-sea neutrino detector at the Mediterranean...

Existence of non-interacting fermion singlets, known as sterile neutrinos, are contextualised in beyond standard model physics. From accommodating oscillation anomalies to play a role of messenger for neutrino mass generation mechanism through type-I seesaw, they have blossomed as a key ingredient with their several mass variants. In addition, being a standard model singlet, they are...

The existence of a sterile neutrino is one of the foremost topics of research in the area of neutrino physics. There are several short-baseline anomalies which hint towards the existence of sterile neutrinos [1]. However, a simplistic theory where oscillation is the only explanation is severely constrained due to null results at other experiments [1, 2]. In this work, we propose to study these...

The establishment of non-zero neutrino masses by the phenomenon of neutrino oscillations provides a clear-cut indication of the existence of neutrino magnetic moments. We provide the neutrino magnetic moments in the presence of right-handed current effects within the Left-Right Symmetric Model (LRSM). The effects of Dirac and Majorana phases on the cancellation of the magnetic moments for...

The ANTARES neutrino telescope and its next-generation offspring, KM3NeT, located in the abyss of the Mediterranean Sea, have been designed to study neutrinos from a variety of sources over a wide range of energies and baselines.

Neutrinos are fundamental yet ill-understood particles in the standard model. The fact that they oscillate among each other is an indication towards non-zero masses of neutrinos. This highlights the limitations of the Standard Model of particle physics, which predicts massless neutrinos. Recent measurements of non-zero reactor angle has also opened up an opportunity for a wide variety of...

We study neutrino oscillations in a rotating spacetime under the weak gravity limit for the trajectories of neutrinos which are constrained in the equatorial plane. Using the asymptotic form of the Kerr metric, we show that the rotation of the gravitational source non-trivially modifies the neutrino phase. We find that the oscillation probabilities deviate significantly from the corresponding...

The strong statistical significance of an observed electron-like event excess in the MiniBooNE (MB) experiment, along with an earlier similar excess seen in the Liquid Scintillator Neutrino Detector (LSND), when interpreted in conjunction with recent MicroBooNE results may have brought us to the cusp of new physics discoveries. This has led to many attempts to understand these observations,...

278. Sterile neutrino inclusion resolves the octant degeneracy in presence of resonant matter effectMr Supriya Pan (Physical Research Laboratory)14/12/2022, 16:30Talk
Results of experiments like LSND and MiniBooNE hint toward the possible presence of an additional eV scale sterile neutrino. The addition of a sterile neutrino will significantly impact the standard three flavor neutrino oscillations in particular giving rise to additional degeneracies due to new sterile parameters. In our work, we investigate how sterile neutrino influences the sensitivity to...

A number of anomalous results in short-baseline oscillation may hint at the existence of one or more light sterile neutrino states in the eV mass range and have triggered a wave of new experimental efforts to search for a definite signature of oscillations between active and sterile neutrino states. This new neutrino would have to be a Standard Model gauge singlet, thus it is referred to as...

The mixing among three light active neutrinos is parametrized using the unitary PMNS matrix. If there are additional neutrinos present in Nature which are heavy iso-singlets, then the effective mixing matrix for the light three active neutrinos would be non-unitary. Because of this non-unitary neutrino mixing (NUNM), the oscillation probabilities between the three active neutrinos would be...

Lorentz Invariance Violation (LIV) is a trending topic in Beyond Standard Model Physics. Lorentz symmetry is well established in the low-energy realm of physics. But there are various theories, which suggest its violation at the Planck scale phenomenon. As neutrinos, having tiny mass, are the particles that are breaking down the barriers of the Standard Model, they may be an excellent tool for...

Several beyond standard model phenomena can affect neutrino oscillation prominently. Two such scenarios are non-standard interaction (NSI) and Lorentz Invariance Violation (LIV). Both phenomena have significant impact on neutrino oscillation. Although both theories emerged quite differently, it is still challenging to discriminate between them. The contributions arising from NSI and LIV to the...

For better understanding of neutrino properties, we require precision measurements of the oscillation parameters. Presently the systematic uncertainties in these parameters are large, to which 20-25\% arises due to the lack in the understanding of $\nu/\bar \nu$-N and $\nu/\bar \nu$-A cross sections. Future high precision measurements require the systematic uncertainties to be reduced to...
