Query: Global Analysis of Neutrino Data   In this talk I review the present status of neutrino masses and mixing and
some of their implications for particle physics phenomenology. I first discuss
the minimum extension of the Standard Model of particle physics required to
accommodate neutrino masses and introduce the new parameters present in the
model and in particular the possibility of leptonic mixing. I then describe the
phenomenology of neutrino masses and mixing leading to flavour oscillations and
present the existing evidence from solar, reactor, atmospheric and
long-baseline neutrinos as well as the results from laboratory searches at
short distances. I derive the allowed ranges for the mass and mixing parameters
when the bulk of data is consistently analyzed in the framework of mixing
between the three active neutrinos and obtain as a result the most up-to-date
determination of the leptonic mixing matrix. Then I briefly summarize the
status of some proposed phenomenological explanations to accommodate the LSND
results: the role of sterile neutrinos and the violation of CPT. Finally I
comment how within the present experimental precision it is possible to use the
observation of oscillation patterns to impose severe constraints on the
possible violation of fundamental symmetries in particle physics such as
Lorentz invariance or the weak equivalence principle.
