Neutrino particles

Neutrino is a neutral elementary particle spin 1 / 2, very easy, however with mass greater than 0, participating only in weak interactions mediated processes and gravity. Neutrino is a lepton.
Each neutrino, the interaction with other particles can become associated with leptons only.
Neutrinos are so widespread in the universe as photons and are created in: beta decay, electron capture and the ions, the decay of elementary particles. However, the specific property of neutrino is its interaction with matter very little: it is the weakest interaction of all known interactions of nuclear physics. Therefore, although widespread, neutrino detection is extremely difficult, it can pass through all bodies to “normal” (such as a macromolecule, a metallic object, the human body, sun, clouds of intergalactic cosmic), but not interact meet with them and without any hindrance.
This property has made in recent years to win huge neutrino particles for astronomy and astrophysics in importance, making it possible to detect their exact cosmic source (eg Sun’s core, the region behind cosmic clouds opaque to light, etc.) by means of devices large, complex and special, which can be considered as telescopes.
