Neutrinos – The reason why we are here?

Abstract: Neutrinos some of the most abundant particles in the Universe, but very little is known about them. They have no electric charge, are almost massless and fly through planets and stars without taking much notice. Nevertheless, they may be the most important particle to understand the state the university is in now. We have uncovered over the last decades, some of their remarkable properties: Neutrinos exist in three different types (flavours) and they can transform from one flavour to another. This has been studied with naturally produced neutrinos or using nuclear reactors and accelerators. We have first indications that neutrinos cannot only transform from one flavour to another, but that this transformation is different for neutrinos and their anti-particles (anti-neutrinos). If confirmed, neutrinos may hold the key to understand why there is more matter than anti-matter in the universe. They may be the very reason why we are here.
