In this article, we review the status of the tension between the long-baseline accelerator neutrino experiments T2K and NO$\nu$A. The tension arises mostly due to the mismatch in the appearance data of the two experiments. We explain how…
The Tokai-to-Kamioka (T2K) neutrino experiment measures neutrino oscillations by using an almost pure muon neutrino beam produced at the J-PARC accelerator facility. The T2K muon monitor was installed to measure the direction and stability…
The SuperKamiokande group assert that they have found an oscillatory signature in atmospheric neutrinos through the analysis of \textit{Fully Contained Events} and \textit{Partially Contained Events}. We have performed an $L/E$…
New atmospheric neutrino results from Super-Kamiokande are presented. Results from Kamiokande on upward going muons are also presented. All these data, together with the Kamiokande atmospheric neutrino data give evidence for neutrino…
Neutrino oscillation scenarios involving large angle $\nu_{\mu} \to \nu_e$ oscillations are disfavoured in the parameter range $\Delta m^2/eV^2 >~ 10^{-3}$ by recent results from the CHOOZ reactor-based $\bar{\nu}_e$ disappearance…
In the last decades, the results from a number of short-baseline neutrino experiments and the reanalysis of previous reactor experiments with updated antineutrino fluxes suggest some incompatibility with the standard three-neutrino model. A…
The T2K experiment has performed a search for $\nu_e$ disappearance due to sterile neutrinos using $5.9 \times 10^{20}$ protons on target for a baseline of $280 m$ in a neutrino beam peaked at about $500 MeV$. A sample of \nu_e CC…
Neutrino physics is an experimentally driven field. So, we investigate the different detection techniques available in the literature and study the various neutrino oscillation experiments in a chronological manner. Our primary focus is on…
We study the possibilities offered by muon storage rings for tau-neutrino appearance experiments due to nu_mu to nu_tau and nu_e to nu_tau oscillations. Tau event rates for such experiments are first discussed with a view to examining their…
This paper summarizes recent (as of SSI-02, in some cases updated in November, 2002) results from the Super-Kamiokande and K2K experiments. The interpretation of Super-Kamiokande results on atmospheric and solar neutrinos provides strong…
This paper presents the results of oscillation analysis in K2K experiment. The results show indications of neutrino oscillation and give a new constraint on the oscillation parameters. The difference of neutrino masses squared $\Delta m^2$…
We estimate CP violation for several experimental facilities studying neutrino oscillations. We also estimate the probability of $\nu_{\mu}$ to $\nu_{e}$ conversion, using values of the parameter $\theta_{13}$ within the known limits, in…
The discovery of neutrino oscillations and the large mixing parameters in the Pontecorvo Maki Nakagawa Sakata matrix has opened a window to search for CP-violation in neutrinos. Two long-baseline neutrino experiments, DUNE and…
A strong body of evidence now exists for atmospheric nu_mu disappearance oscillations. Such disappearance could be explained by oscillations to either nu_tau or a ``sterile'' neutrino (nu_s). Super-Kamiokande uses three different methods to…
We study the earth matter effects in the Tokai-to-Kamioka-and-Korea experiment (T2KK), which is a proposed extension of the T2K (Tokai-to-Kamioka) neutrino oscillation experiment between J-PARC at Tokai and Super-Kamiokande (SK) in Kamioka,…
The T2K experiment observes indications of $\nu_\mu\rightarrow \nu_e$ appearance in data accumulated with $1.43\times10^{20}$ protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino…
The current case for atmospheric $\nu_\mu$ oscillations into active or sterile neutrinos is reviewed. It is argued that neither the study of neutral current events at Super-Kamiokande, nor the information obtained from future long baseline…
Recent results show that atmospheric $\nu_\mu$ oscillate with $\delta m^2 \simeq 3 \times 10^{-3}$ eV$^2$ and $\sin^2{2\theta_{atm}} \simeq 1$, and that conversion into $\nu_e$ is strongly disfavored. The Super-Kamiokande (SK)…
This talk reports the latest indications of an anomaly in the measurements of atmospheric neutrinos. New results from Soudan-2 and Super-Kamiokande provide evidence that the ratio of nu_mu to nu_e interactions is not as expected. High…
Neutrino oscillations are clear evidence for physics beyond the standard model. The goal of next-generation neutrino oscillation experiments is to find a non-zero $\theta_{13}$, the last mixing matrix element for which we only know an upper…
