The need for writing a self-contained comprehensive book on the physics of neutrino interactions had been in our minds for a long time, while teaching various graduate courses in high energy physics and nuclear physics and conducting research in the field of neutrino physics at the Aligarh Muslim University. We also realized the need for such a book while attending many topical workshops, conferences, and short-term schools like NuFact, NuInt, NuSTEC, etc., held in the USA, Europe, Japan, and elsewhere in the area of neutrino physics and while responding to questions asked by the young researchers in many formal and informal discussions. The aforementioned scientific events bring together research students and senior scientists working on various aspects of neutrino physics common to nuclear physics, particle physics, and astrophysics, which make the subject interdisciplinary. In recent times, the research activity in the field of neutrino physics, around the world, and its applications in the other areas of physics has attracted a large number of students to this field. It was, therefore, felt that this is an appropriate time to write a book on the physics of neutrino interactions focusing on introducing the basic mathematical and physical concepts and methods with the help of simple examples to illustrate the calculation of various neutrino processes relevant for applications in particle physics, nuclear physics, and astrophysics, for the benefit of all those interested in learning the subject.
The main aim of the book is to present a pedagogical account of the physics of neutrino interactions, with balance among its theoretical and experimental aspects, for describing various neutrino scattering processes from leptons, nucleons, and nuclei used in studying neutrino properties like its mass, charge, magnetic moment, and the newly discovered phenomenon of neutrino mixing and oscillations. The book is intended primarily for graduate students and young post-doctoral research scientists working in neutrino physics but it can also be used by advanced undergraduates who have some exposure to basic courses in special theory of relativity, quantum mechanics, nuclear physics, particle physics, and are interested in neutrino physics.
