The world's first neutrino observation in a hydrogen bubble chamber was found Nov. 13, 1970, on this historical photograph from the Zero Gradient Synchrotron's 12-foot bubble chamber. The invisible neutrino strikes a proton where three particle tracks originate (right). The neutrino turns into a muon, the long center track. The short track is the proton. The third track is a pi-meson created by the collision. This picture is rotated to the original photograph and includes a colored overlay which shows the visible and invisble tracks of the decay. Also the weak neutrino decay is shown on the right hand side. From: Argonne National Laboratory, http://www.anl.gov/Science_and_Technology/History/Anniversary_Frontiers/86photo.html

NeutrinoNeutrinos sind elektrisch neutrale Elementarteilchen mit sehr geringer Masse. Im Standardmodell der Elementarteilchenphysik existieren drei Arten (Generationen) von Neutrinos: Elektron-, Myon- und Tau-Neutrinos. Jede Neutrino-Generation besteht aus dem Neutrino selbst und seinem Anti-Neutrino. Der Name Neutrino wurde von Enrico Fermi für das von Wolfgang Pauli postulierte Teilchen vorgeschlagen und bedeutet kleines neutrales Teilchen. .. weiterlesen
