AN OVERVIEW OF NEUTRINO PROPERTIES

Physics

Neutrinos are among the most abundant elementary particles in the universe. If we want to understand the Universe, then we need to know about the neutrinos. They are the second most abundant particles after photons. Though learning about the world of neutrinos is not so easy because their interaction with matter is extremely feeble. A brief review on the phenomenon of neutrino oscillation both in vacuum and in medium is studied here. In this work, I have discussed about neutrino experiments mostly natural and artificial neutrino experiments. Marvelous results on neutrino oscillations in the last several years have triggered a lot of enthusiasm and interest in neutrinos, from experimental as well as theoretical point of view. One of the most important facts is that, neutrino physics is a data driven field - for several years now, new data are pouring at an outstanding rate. Our understanding of neutrinos has improved dramatically in the past ten years and there is no doubt that neutrino oscillation is an exclusive example of experimental evidence for physics beyond the Standard Model of particle physics. Neutrino physics is a very intense field of research having implications in different branches of physics, such as high energy physics, quantum field theory, cosmology, astrophysics, nuclear physics and geophysics. Spectacular results on neutrino oscillations in the last several years have triggered a lot of interest in neutrinos, from experimental as well as theoretical point of view, and many future neutrino experiments are in preparation or under discussion to sharpen our understanding about these tiny particles. This work addresses several aspects of these issues.
