Neutrino Properties Determined in Oscillation Experiments

Neutrinos are the lightest of known subatomic matter particles in the set of building blocks of matter. In the Standard Model there are three types of neutrinos, associated with respective charged leptons. Prof. F. Reines who was the author of first experiment which detected neutrino said about them, that they are "the smallest part of reality ever invented by human". In the presentation experimental results proving specific features of neutrinos will be presented, as well as some information on neutrino sources and detection techniques. In general neutrino oscillations can occur only when the mixing parameters, including squere of mass difference, are non-zero. Therefore, observation of neutrino oscillations proves that neutrinos are not massless. With several experiments contributing, one can show that we know the oscillation parameters quite well. The most recent oscillation results from neutrinos and antineutrinos will be presented and also future long baseline oscillation projects in short and long time scale will be briefly mentioned.
