Neutrinos (II)
- Concha Gonzalez-Garcia (ICREA-UB and YITP-Stony Brook)
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...
