Neutrino physics: from open questions to physics beyond the Standard Model
One of the most compelling discoveries in particle physics of the past 40 years is that of neutrino oscillations and consequently neutrino masses, marked by the Nobel Prize in Physics in 2015. This is so far the only particle physics evidence that the Standard Model is incomplete and, together dark matter and the baryon asymmetry of the Universe, guides us in the search for the ultimate theory of particles and interactions. Despite the impressive advance in determining the properties of massive neutrinos, a complete picture is still lacking. In this talk, I will review the current status and will discuss the open questions and the broad experimental programme that will address them by the end of this decade. Going beyond the standard scenario of 3 neutrino mixing, I will also discuss (unconfirmed) anomalies that have emerged in this field and still lack a compelling explanation: from MiniBooNE to reactor neutrino results. I will ask the question if these puzzling results can hint towards a new Standard Model of particle physics at low energies.
