The branch of physics which deals with the fundamental properties of sub-atomic particles that constitute radiation and matter is known as particle physics. Few of these particles are photons, neutrons, protons, electrons, muons, and neutrinos. They exhibit a wave particle duality and their dynamics are governed by the principles of quantum mechanics. Properties such as electrical charge, spin, mass and magnetism are studied by making use of quantum state vectors in a Hilbert space. Particle physics finds extensive applications in the fields of medicine, computer science, electronics and national security. Different approaches, evaluations, methodologies and advanced studies on particle physics have been included in this book. Some of the diverse topics covered herein address the varied branches that fall under this category. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of this subject.
"Unique in its coverage of all aspects of modern particle physics, this textbook provides a clear connection between the theory and recent experimental results, including the discovery of the Higgs boson at CERN.

Comprehensive, up-to-date textbook, integrating recent experimental results, including discovery of the Higgs boson, to convey the excitement of the field to undergraduate and graduate students. Physical theory is made accessible with coverage of underlying principles, full mathematical derivations, worked examples of experimental applications, and end-of-chapter problems.
For scientific, technological and organizational reasons, the end of World War II (in 1945) saw a rapid acceleration in the tempo of discovery and understanding in nuclear physics, cosmic rays and quantum field theory, which together triggered the birth of modern particle physics. The first fifteen years (1945-60) following the war's end ? the ?Startup Period? in modern particle physics -witnessed a series of major experimental and theoretical developments that began to define the conceptual contours (non-Abelian internal symmetries, Yang-Mills fields, renormalization group, chirality invariance, baryon-lepton symmetry in weak interactions, spontaneous symmetry breaking) of the quantum field theory of three of the basic interactions in nature (electromagnetic, strong and weak). But it took another fifteen years (1960-75) ? the ?Heroic Period? in modern particle physics ? to unravel the physical content and complete the mathematical formulation of the standard gauge theory of the strong and electroweak interactions among the three generations of quarks and leptons. The impressive accomplishments during the ?Heroic Period? were followed by what is called the ?period of consolidation and speculation (1975-1990)?, which includes the experimental consolidation of the standard model (SM) through precision tests, theoretical consolidation of SM through the search for more rigorous mathematical solutions to the Yang-Mills-Higgs equations, and speculative theoretical excursions ?beyond SM?.Within this historical-conceptual framework, the author ? himself a practicing particle theorist for the past fifty years ? attempts to trace the highlights in the conceptual evolution of modern particle physics from its early beginnings until the present time. Apart from the first chapter ? which sketches a broad overview of the entire field ? the remaining nine chapters of the book offer detailed discussions of the major concepts and principles that prevailed and were given wide currency during each of the fifteen-year periods that comprise the history of modern particle physics. Those concepts and principles that contributed only peripherally to the standard model are given less coverage but an attempt is made to inform the reader about such contributions (which may turn out to be significant at a future time) and to suggest references that supply more information. Chapters 2 and 3 of the book cover a range of topics that received dedicated attention during the ?Startup Period? although some of the results were not incorporated into the structure of the standard model. Chapters 4-6 constitute the core of the book and try to recapture much of the conceptual excitement of the ?Heroic Period?, when quantum flavordynamics (QFD) and quantum chromodynamics (QCD) received their definitive formulation. [It should be emphasized that, throughout the book, logical coherence takes precedence over historical chronology (e.g. some of the precision tests of QFD are discussed in Chapter 6)]. Chapter 7 provides a fairly complete discussion of the chiral gauge anomalies in four dimensions with special application to the standard model (although the larger unification models are also considered). The remaining three chapters of the book (Chapters 7-10) cover concepts and principles that originated primarily during the ?Period of Consolidation and Speculation? but, again, this is not a literal statement. Chapters 8 and 9 report on two of the main directions that were pursued to overcome acknowledged deficiencies of the standard model: unification models in Chapter 8 and attempts to account for the existence of precisely three generations of quarks and leptons, primarily by means of preon models, in Chapter 9. The most innovative of the final three chapters of the book is Chapter 10 on topological conservation laws. This last chapter tries to explain the significance of topologically non-trivial solutions in four-dimensional (space-time) particle physics (e.g. 't Hooft-Polyakov monopoles, instantons, sphalerons, global SU(2) anomaly, Wess-Zumino term, etc.) and to reflect on some of the problems that have ensued (e.g. the ?strong CP problem? in QCD) from this effort. It turns out that the more felicitous topological applications of field theory are found ? as of now ? in condensed matter physics; these successful physical applications (to polyacetylene, quantized magnetic flux in type-II low temperature superconductivity, etc.) are discussed in Chapter 10, as a good illustration of the conceptual unity of modern physics.

This book is written for students and scientists wanting to learn about the Standard Model of particle physics. Only an introductory course knowledge about quantum theory is needed. The text provides a pedagogical description of the theory, and incorporates the recent Higgs boson and top quark discoveries. With its clear and engaging style, this new edition retains its essential simplicity. Long and detailed calculations are replaced by simple approximate ones. It includes introductions to accelerators, colliders, and detectors, and several main experimental tests of the Standard Model are explained. Descriptions of some well-motivated extensions of the Standard Model prepare the reader for new developments. It emphasizes the concepts of gauge theories and Higgs physics, electroweak unification and symmetry breaking, and how force strengths vary with energy, providing a solid foundation for those working in the field, and for those who simply want to learn about the Standard Model.
Introduces the fundamental concepts pertaining to the basic topics of relativity, quantum mechanics and statistical mechanics along with the important sub-fields of physics, namely atomic, nuclear and solid state physics. Superconductivity and optoelectronics, lasers and nanoparticles are also introduced. A key feature of the book is the introduction of latest applications based on x-rays, lasers, radioactivity and condemnsed matter.
Most of the progress made in particle physics during the last two decades has to led to the formulation of the so called ?Standard Model? of elementary particles and its quantitative experimental test. The book deals with this progress but includes chapters which provide the necessary background material to modern particle physics.Particle physics forms an essential part of physics curriculum. This is a textbook but will also be useful for people working in this field and for nuclear physicists, particularly those who work on topics concerning interface between nuclear and particle physics. The book is designed for a semester course for senior undergraduates and a semester course for graduate students. Formal quantum field theory is not used; a knowledge of non-relativistic quantum mechanics is required for some parts of the book; but for the remaining parts the familiarity with the Dirac equation is essential. However, some of these topics are included in the appendix.
