Abstract

Since 1988's we aware we can only understand the measurement of neutrinos coming from different directions if we invoke the existence of the so called neutrino oscillation. This mechanism made an initial muon neutrino to be converted to electron neutrino after the neutrino travelled a distance L. The interpretation of evolution equation is made due quantum field theory formalism. We will work in some analogy, that the same evolution equation for neutrinos can be written as a system of spin 1/2 particles under the magnetic field force. Our purpose is to create a better understanding of the mechanism of neutrino oscillation showing that is a very good example of the consequences of Quantum Mechanics. (AU)
