| 3 | == Neutrino's phenomenology for 3rd year students == |

| 4 | |

| 5 | This is a workshop intended for 3rd year physics majors on neutrino's oscillations. |

| 6 | Tee prerequisites are Quantum Mechanics and Special relativity. No Relativistic Quantum Mechanics or QFT needed. |

| 7 | The aim is to understand the basics of the oscillation physics, to be able to understand the experimental plots and |

| 8 | eventually address the debate which was going a few years ago on the famous factor of two. |

| 22 | 1. Derive the expression for the probability that a neutrino created with flavor l at time t=0 evolves to a different flavor l' after a time t. |

| 23 | 1. Write it in terms of a distance from the creation point. Assume neutrino's move (almost) at the speed of light. The probability depends on the neutrino's masses: How? |

| 24 | 1. Find the explicit formulas in the case of two flavor oscillations. |

| 25 | 1. Consider unstable neutrinos |
