1 Neutrinos Jason Cook

2 Topics of Interest Neutrinos  History  Sources  Detection  Solar Neutrino Problem  Neutrino Oscillation  Practicality of Neutrinos

3 Neutrinos Leptons  Tau  Muon  Electron  Corresponding neutrinos Baryons Fermions υ Properties of Leptons

4 History Neutrino Timeline Important Figures  Wolfgang Pauli  Enrico Fermi

5 Sources of Neutrinos Natural Neutrino Sources  Beta Decay  Stellar  Solar

6 Beta Decay n o => p + + e - + υ e Energy + p + => n o + e + + υe

7 Stellar Sources Natural Fusion Reactions Type II Supernovae Cosmic Background

8 Detection Cerenkov radiation Heavy Water Location location location

9 Super-Kamiokande Detector

10 The Solar Problem Early predictions of solar neutrinos Attempts at detection  Results Rationalization of findings Rectification of the problem http://spaceflightnow.com/news/n0106/20sno/

11 Neutrino Oscillation Neutrinos can oscillate Random probability of measuring a neutrino as one of the three flavors

12 Practicality of Neutrinos Unlike EM waves, neutrinos are virtually unaffected by stellar medium Stellar studies Galactic Studies Quantum Studies
