The branch of physics which focuses on the study of the nature of
particles which comprise radiation and matter is known as particle
physics. It also studies the fundamental interactions which are
necessary to explain the behavior of the irreducibly small particles.
Some of the subatomic particles studied within this field are protons,
electrons, neutrons, quarks and leptons. The classification of these
particles is done using the theory of the Standard Model of particle
physics. There are numerous other theories which are also studied within
this field like quantum field theory, effective field theory and lattice
field theory. Particle physics is applied in varied sectors such as
medicine, computing and national security. This book includes some of
the vital pieces of work being conducted across the world, on various
topics related to particle physics. It is an upcoming field of science
that has undergone rapid development over the past few decades. This
book will help the readers in keeping pace with the rapid changes in
this field.
