The need for writing a self-contained comprehensive book on the physics ofneutrino interactions had been in our minds for a long time, while teachingvarious graduate courses in high energy physics and nuclear physics andconducting research in the field of neutrino physics at the Aligarh MuslimUniversity. We also realized the need for such a book while attending manytopical workshops, conferences, and short-term schools like NuFact, NuInt,NuSTEC, etc., held in the USA, Europe, Japan, and elsewhere in the area ofneutrino physics and while responding to questions asked by the youngresearchers in many formal and informal discussions. The aforementionedscientific events bring together research students and senior scientistsworking on various aspects of neutrino physics common to nuclear physics,particle physics, and astrophysics, which make the subjectinterdisciplinary. In recent times, the research activity in the field ofneutrino physics, around the world, and its applications in the other areasof 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 thephysics of neutrino interactions focusing on introducing the basicmathematical and physical concepts and methods with the help of simpleexamples to illustrate the calculation of various neutrino processesrelevant for applications in particle physics, nuclear physics, andastrophysics, for the benefit of all those interested in learning thesubject.

The main aim of the book is to present a pedagogical account of the physicsof neutrino interactions, with balance among its theoretical andexperimental aspects, for describing various neutrino scattering processesfrom leptons, nucleons, and nuclei used in studying neutrino properties likeits mass, charge, magnetic moment, and the newly discovered phenomenon ofneutrino mixing and oscillations. The book is intended primarily forgraduate students and young post-doctoral research scientists working inneutrino physics but it can also be used by advanced undergraduates who havesome exposure to basic courses in special theory of relativity, quantummechanics, nuclear physics, particle physics, and are interested in neutrinophysics.
