Title:  Neutrino physics and dark sectors

Abstract: Neutrino physics, pursued at an increasing pace around the world, has 

already brought us important knowledge about nature. The discovery of neutrino masses and mixings, although not a total surprise, is not imposed by the gauge structure of the Standard Model. Can we use the continuing investment in neutrino physics to learn more about physics beyond Standard Model? I will show how the existing and planned experiments provide unique possibility to probe dark sectors, i.e. new extensions of the Standard Model that contains light weakly coupled states. I will also discuss the role of theoretical physics in guiding these efforts.
