Borexino is a massive, calorimetric liquid scintillator detector installed at the underground Gran Sasso Laboratory. With its unprecedented radiopurity levels achieved in the core of the detection medium, it is the only real time experiment in operation able to study solar neutrino interactions in the challenging sub-MeV energy region.
The recent precise measurement of the 7Be solar neutrino...

Neutrino event generators play an important role in the design and execution of neutrino experiments. In this talk I will describe several programs that simulate neutrino-nucleus interactions in the 1-100 GeV energy regime, focussing in particular on a discussion of the underlying physics models and identifying key assumptions.

ICARUS-T600 is the first example of an innovative detection technology, the liquid Argon TPC, which
is a sort of "electronic bubble chamber", potentially scalable to huge masses.
The excellent topology reconstruction, tracking and particle identification capabilities,
together with the calorimetric measurement of deposited energy, make the LAr-TPC an ideal detector for
the study of rare...

The T2K (Tokai to Kamioka) experiment is a long baseline neutrino oscillation experiment designed to probe the θ13 neutrino mixing parameter by looking for the appearance of νe in an almost pure νμ beam. The concurrent measurement of νμ disappearance allows refined measurements of the atmospheric Δm2 and of the θ23 mixing parameters. A neutrino beam is produced at the Japan Proton Accelerator...

What is the origin of the observed fermion masses and mixing parameters? Neutrinos, with their small mass and large mixing, contribute an important part of this flavour puzzle. Could they possibly also provide the key towards its solution? We review the present status and discuss some recent developments regarding the flavour puzzle, from the neutrino physics perspective.

Current experimental data on the neutrino parameters is in good
agreement with tribimaximal mixing and may indicate the presence of an
underlying family symmetry. For 76 flavor groups, we perform a

Standard Model plus up to three flavon fields, and the effective
Lagrangian contains all terms of mass dimension <=6. We find...

In this talk I will consider an extension of the Standard Model by heavy right-handed neutrinos and a second Higgs doublet. In the decoupling limit of the extra particles, this model provides an explanation for the small neutrino masses and for the mild hierarchy observed between the atmospheric and solar mass splittings without jeopardizing any of the successes of the Standard Model. Finally...

We investigate numerically how accurately one could constrain the strengths of different short-range contributions to neutrinoless double beta decay in effective field theory. Depending on the outcome of near-future experiments yielding information
on the neutrino masses, the corresponding bounds or estimates can be stronger or weaker. A particularly interesting case, resulting in strong...

Under certain conditions, the strength of the charged (CC) and neutral current (NC) weak interactions of the Standard Model particles with the heavy RH neutrinos can be large enough to allow the production of the latter at the LHC, opening...
