In this work we aim to introduce the physics of the neutrino, from its first proposal by Wolfgang Pauli, until the experimental evidence of flavor oscillation, which gave the 2015 Nobel Prize in Physics to Arthur McDonald and Takaaki Kajita. After we present the so called Solar Neutrino Problem, which is based on the fact that experiments to detect electronic-neutrinos from the Sun have shown a deficit in the expected values, we will develop the physics behind the model of flavor oscillation due to difference in mass, focusing on the two flavor case between νe and νa, where νa is a non-electronic neutrino flavor. In this model we use the mixing matrix to compose a coherent neutrino flavor state using what is called neutrino mass eigenstates, and after finding the probabilities of survival, we discuss how is this evidence contributing to the development of the physics beyond standard model
