Since the discovery of neutrino oscillations twenty years ago, the field has made rapid progress in measuring the underlying mixing and mass splitting parameters that govern the oscillations. Neutrino oscillations have been observed several modes and the next steps, which involve establishing the pattern of neutrino masses and whether neutrino mixing violates CP symmetry are well underway. I...
Light sterile neutrinos with a mass around 1 eV have been studied for many years as a possible explanation of the so called short-baseline neutrino oscillation anomalies. I will review our current knowledge on the light sterile neutrino in the 3+1 model, discussing the status of the most relevant searches at neutrino oscillation experiments and the impact that
the new neutrino would have on cosmology.
We present a model where a low scale dynamical mechanism gives rise to neutrino masses. In this model new light particles, charged under a dark U(1) gauge symmetry, communicate with the Standard Model particles only via mixing: flavour mixing (neutrinos), mass mixing (scalars) and kinetic mixing (a new light mediator). We discuss how this model can provide a possible explanation to MiniBooNE...
