We investigate the effect induced by neutrino oscillation on the dark matter indirect detection signal which consists in a muon neutrino flux produced by neutralino annihilation in the Earth core. We consider the neutrino oscillation parameters relevant to the atmosferic neutrino deficit, both in the νμ → ντ and νμ → νs cases.

We consider the neutrino oscillation parameters relevant to the atmosferic neutrino deecit, both in the ! and ! s cases.
The current status of neutrino oscillation searches with reactors and accelerators is reviewed. An outlook, especially on future long baseline neutrino oscillation projects, is given.
Atmospheric neutrino and solar neutrino data from the first phase of Super-Kamiokande (SKI) are presented. The observed data are used to study atmospheric and solar neutrino oscillations. Zenith angle distributions from various atmospheric neutrino data samples are used to estimate the neutrino oscillation parameter region. In addition, a new result of the L/E measurement is presented. A dip in...
We present an analysis of the global neutrino oscillation data in terms of four-neutrino mass schemes. We find that the strong preference of oscillations into active neutrinos implied by the latest solar as well as atmospheric neutrino data allows to rule out (2+2) mass schemes, whereas (3+1) schemes are strongly disfavoured by shortbaseline experiments. Our analysis shows that four-neutrino os...
The unknown neutrino mixing angle θ13 is one of the most important goals in current neutrino experiments. For the next generation of long baseline neutrino oscillation experiments, T2K and NOvA, the precise measurement of neutrino-nucleus cross sections in the few GeV energy range is an essential ingredient in the interpretation of neutrino oscillation signals. Neutral current neutral-pion prod...
We make a global vacuum neutrino oscillation analysis of solar neutrino data, including the seasonal and energy dependence of the recent Super–Kamiokande 708day results. The best fit parameters for νe oscillations to an active neutrino are δm = 4.42 × 10 eV, sin 2θ = 0.93. The allowed mixing angle region is consistent with bi–maximal mixing of three neutrinos. Oscillations to a sterile neutrino...
This paper reviews the constraints imposed on the solar neutrino mixing parameters by data collected by the Sudbury Neutrino Observatory (SNO). The SNO multivariate analysis is reviewed. The global solar neutrino analysis is emphasized in terms of matter-enhanced oscillation of two active flavors. An outline of how SNO uses the data to produce oscillation contour plots and how to include the re...
Muon neutrino disappearance probability as a function of neutrino flight length L over neutrino energy E was studied. A dip in the L/E distribution was observed in the data, as predicted from the sinusoidal flavor transition probability of neutrino oscillation. The observed L/E distribution constrained nu(micro)<-->nu(tau) neutrino oscillation parameters; 1.9x10(-3)<Deltam(2)<3.0x10(-3) eV(2) a...
We discuss the measurement of the neutrino oscillation parameters at future long baseline experiments in terms of the motivation of the experiments, the quantities of interest from the theoretical point of view, the phenomenology of these experiments, and the experiment choice. We illustrate the oscillation physics potential of a neutrino factory, as a representative for the most challenging te...
