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...
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 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. One of the principal goals of these experiments is to determine Earth-matter effects stemming from the energy and zenith angle dependence of atmospheric neutrinos in...
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...
NOvA is a two-detector, long-baseline neutrino oscillation experiment located at Fermilab, Batavia, IL, USA. It is primarily designed to constrain neutrino oscillation parameters using muon neutrino (anti-neutrino) disappearance data and electron neutrino (anti-neutrino) appearance data. NOvA detects neutrinos from Fermilabโs Neutrinos at Main Injector (NuMI) beamline. The unoscillated muon...
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,...
Neutrino Oscillation has been one of the most promising sources of physics beyond the standard model in many experimental searches so far. Various short and long baseline experiments have been developed using the most advanced detector technologies to detect this elusive particle. NOvA is one such experiment designed with the initial aim of looking at the possibility of the oscillation of muon...
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...
The information about Earth's internal structure comes from indirect probes such as seismic studies and gravitational measurements. The density distribution inside the Earth, incorporated in the Preliminary Reference Earth Model (PREM), is estimated from the model-dependent empirical relations having assumptions based on the Earth's temperature, pressure, composition, and elastic properties,...
Neutrinoless double-$\beta$ decay (0$\nu \beta \beta$) is the most sensitive
experimental probe to answer the question whether neutrinos have Majorana or Dirac
nature. The observation of (0$\nu \beta \beta$) would not only establish the Majorana
nature of neutrinos, but also provide a measurement of effective mass and probe the
neutrino mass hierarchy. The latest precise neutrino...
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...
The study of tauon($\tau$-lepton) is one of the topics of current interest as its understanding is required for various important aspects such as to test the lepton flavor universality, for the accurate measurement of the neutrino oscillation parameters, to reduce the uncertainties in the $\nu_l-$nucleus cross section measurements, etc. Since the tauon has higher threshold and very short...
Indian Scintillator Matrix for Reactor Anti-Neutrinos (ISMRAN) experiment is a very short-baseline (~ 13 m from the reactor core) and above-ground reactor anti-neutrino experiment, aiming to measure the energy spectrum of anti-neutrinos from the Dhruva research reactor, BARC, Mumbai. ISMRAN experiment is also sensitive to searching for sterile neutrino and monitoring the reactor thermal...
The goal of the Short Baseline Neutrino (SBN) program is to definitively address observed anomalies that may originate from short baseline neutrino oscillations and to search for evidence of the existence of light sterile neutrinos with unprecedented sensitivity in eV^2 mass range. In the SBN experiment, the near detector (SBND) is close to the source and the intermediate detector is...
The proposed magnetized iron calorimeter (ICAL) by the INO collaboration is a 51 kTon detector made up of 151 layers of 56 mm thick iron having an air gap of 40 mm in between each iron layer where Resistive Plate Chambers (RPCs), active detectors providing position and timing information, will be placed. ICAL is designed to detect muons generated by the charge current interaction of the...
The Accelerator Neutrino Nucleon Interaction Experiment (ANNIE) at Fermilab is designed to measure the final-state neutron multiplicity of the neutrino-nucleus interaction. The ANNIE's Gadolinium-loaded water Cherenkov detector is situated in the Booster Neutrino Beam (BNB) at Fermilab. The measurements of ANNIE are crucial for future long-baseline neutrino experiments since a better...
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...
