The Higgs Hunter's Guide is a definitive and comprehensive guide to the physics of Higgs bosons. In particular, it discusses the extended Higgs sectors required by those recent theoretical approaches that go beyond the Standard Model, including supersymmetry and superstring-inspired models.

This book is devoted to the presentation of rigorous mathematical results in the kinetic theory of a gas of hard spheres. Recent developments as well as classical results are presented in a unified way, such that the book should become the standard reference on the subject. There is no such book available at present. The reader will find a systematic treatment of the main mathematical results, a discussion of open problems, and a guide to the existing literature. There is a rigorous and comprehensive presentation of strict validation of the Boltzmann equations, global existence theory, and the fluid-dynamical limits. The authors also review and discuss classical derivation and properties of the Boltzmann equation, particle simulation methods, and boundary conditions.

This author's second volume introduces basic principles of interpreting infrared spectral data, teaching its readers to make sense of the data coming from an infrared spectrometer. Contents include spectra and diagnostic bands for the more common functional groups as well as chapters on polyester spectra and interpretation aids. Discussions include: o science of infrared interpretation o light and molecular vibrations o how and why molecules absorb infrared radiation o peak heights, intensities, and widths o hydrocarbons, carbonyl groups, and molecules with C-N bonds o polymers and inorganic molecules o the use of atlases, library searching, spectral subtraction, and the Internet in augmenting interpretation Each chapter presents an introduction to the nomenclature and structure of a specific functional group and proceeds with the important diagnostic bands for each group. Infrared Spectral Interpretation serves both novices and experienced practitioners in this field.

Photonic crystal fibers, also known as microstructured or holey fibers, have recently generated great interest in the scientific community thanks to the new ways provided to control and guide light, not obtainable with conventional optical fibers. Proposed for the first time in the 90 s, photonic crystal fibers have driven an exciting and irrepressible research activity all over the World, starting in the telecommunication field and then touching metrology, spectroscopy, microscopy, astronomy, micromachining, biology and sensing. This book is intended to provide an expert guidance through the properties of photonic crystal fibers, with a specific focus on the telecommunication aspects. The authors believe that photonic crystal fibers can revolutionize the field of guided optics and its applications, especially when considering signal processing and specific functions rather than the usage in long distance transmission. They provide a deep analysis of how the physical and...

A greatly revised and expanded account of phaselock technology The Third Edition of this landmark book presents new developments in the field of phaselock loops, some of which have never been published until now. Established concepts are reviewed critically and recommendations are offered for improved formulations. The work reflects the author's own research and many years of hands-on experience with phaselock loops. Reflecting the myriad of phaselock loops that are now found in electronic devices such as televisions, computers, radios, and cell phones, the book offers readers much new material, including: * Revised and expanded coverage of transfer functions * Two chapters on phase noise * Two chapters examining digital phaselock loops * A chapter on charge-pump phaselock loops * Expanded discussion of phase detectors and of oscillators * A chapter on anomalous phaselocking * A chapter on graphical aids, including Bode plots,...

This book describes how modern quantum field theory is capable of treating not only quantum field particles, but also objects with classical and quantum mechanical degrees of freedom, including thermal degrees of freedom. It thus provides a unified overviw of many areas of physics on the basis of the concept of macroscopic quantum vacuum. - This text refers to an out of print or unavailable edition of this title.

There is an ill-concealed skeleton in the closet of physics: "As they are currently formulated, general relativity and quantum mechanics cannot both be right." Each is exceedingly accurate in its field: general relativity explains the behavior of the univrse at large scales, while quantum mechanics describes the behavior of subatomic particles. Yet the theories collide horribly under extreme conditions such as black holes or times close to the big bang. Brian Greene, a specialist in quantum field theory, elieves that the two pillars of physics can be reconciled in superstring theory, a theory of everything. Superstring theory has been called "a part of 21st-century physics that fell by chance into the 20th century." In other words, it isn't all wored out yet. Despite the uncertainties--"string theorists work to find approximate solutions to approximate equations"--Greene gives a tour of string theory solid enough to satisfy the scientifically literate. Though Ed Witten...

It's not a scientific truth that has come into question lately but the truth--the very notion of scientific truth. Bringing a reasonable voice to the culture wars that have sprung up around this notion, this book offers a clear and constructive response to those who contend, in parodies, polemics and op-ed pieces, that there really is no such thing as verifiable objective truth--without which there could be no such thing as scientific authority. A distinguished physicist with a rare gift for making the most complicated scientific ideas comprehensible, Roger Newton gives us a guided tour of the intellectual structure of physical science. From there he conducts us through the understanding of reality engendered by modern physics, the most theoretically advanced of the sciences. With its firsthand look at models, facts, and theories, intuition and imagination, the use of analogies and metaphors, the importance of mathematics (and now, computers), and the "virtual" reality of the physics.

This book is an attempt to explain hardness measurements of metals in terms of some of their more basic physical properties. It does not deal with the atomic and crystalline mechanism of elastic or plastic deformation, but starting with the elastic and plastic characteristics it shows that the hardness behavior of metals may be expressed in terms of these characteristics. It is hoped that this presentation will provide, for physicists, engineers, and metallurgists, a better understanding of what hardness means and what hardness measurements imply. The book places an emphasis on the physical concepts involved, so that the non-mathematical reader may grasp and appreciate the general physical picture without needing to follow the more detailed treatment.

Market: Those involved in laboratory chemical analysis, atmospheric chemistry, and atomic and molecular physics. Long regarded as the standard introduction to the field, Quadrupole Mass Spectrometry and Its Applications provides today's engineers and scientists with an authoritative, wide-ranging overview of the development and uses of quadrupoles. Beginning with the basic operating principles of quadrupole devices, the book moves from general explanations of the actions of radio-frequency fields to descriptions of their utilization in quadrupole mass filters, monopoles, three-dimensional quadrupole ion traps, and various time-of -flight spectrometers. A concluding series of chapters examines fundamental applications of quadrupoles in atomic and subatomic physics, gas chromatography, upper atmospheric research, medicine, and environmental studies.

This updated and expanded version of the very successful first edition offers new chapters on controlling the emission from electronic systems, especially digital systems, and on low-cost techniques for providing electromagnetic compatibility (EMC) for consumer products sold in a competitive market. There is also a new chapter on the susceptibility of electronic systems to electrostatic discharge. There is more material on FCC regulations, digital circuit noise and layout, and digital circuit radiation. Virtually all the material in the first edition has been retained. Contains a new appendix on FCC EMC test procedures.
