Download or read book Search for a Heavy Neutral Particle Decaying to E?, E?, Or ?? in Pp Collisions at {u221A}s written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This Letter presents a search for a heavy neutral particle decaying into an opposite-sign different-flavor dilepton pair, e±?∓, e±?∓, or ?±?∓ using 20.3 fb-1 of pp collision data at √s=8 TeV collected by the ATLAS detector at the LHC. The numbers of observed candidate events are compatible with the standard model expectations. In addition, limits are set on the cross section of new phenomena in two scenarios: the production of ????????? in R-parity-violating supersymmetric models and the production of a lepton-flavor-violating Z' vector boson.

Book Synopsis Cracking the Particle Code of the Universe by : John W. Moffat
Download or read book Cracking the Particle Code of the Universe written by John W. Moffat and published by Oxford University Press. This book was released on 2013-12-13 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the current books that celebrate the discovery of the Higgs boson, Cracking the Particle Code of the Universe is a rare objective treatment of the subject. The book is an insider's behind-the-scenes look at the arcane, fascinating world of theoretical and experimental particle physics leading up to the recent discovery of a new boson. If the new boson is indeed the Higgs particle, its discovery represents an important milestone in the history of particle physics. However, despite the pressure to award Nobel Prizes to physicists associated with the Higgs boson, John Moffat argues that there still remain important data analyses to be performed before uncorking the champagne. John Moffat is Professor Emeritus of Physics at the University of Toronto and a senior researcher at the Perimeter Institute for Theoretical Physics. Well-known for his outside-the-box research on topics such as dark matter, dark energy, and the varying speed of light cosmology (VSL), his new book takes a critical look at the hype surrounding the Higgs boson. In the process, he presents a cogent and often entertaining history of particle physics and an exploration of alternative theories of particle physics that do not feature the Higgs boson, including his own. He gives a detailed and personal description of how theoretical physicists come up with new theories, and emphasizes how carefully experimental physicists must interpret the complex data now coming out of accelerators like the Large Hadron Collider (LHC). The book does not shy away from controversial topics such as the sociology of particle physics. There is immense pressure on projects like the $9 billion LHC to come up with positive results in order to secure funding for the future. Yet to date, the Higgs boson may be the only positive result to emerge from the LHC experiments. The searches for dark matter particles, mini-black holes, extra dimensions, and supersymmetric particles have all come up empty-handed, with serious consequences for theoretical physics, including string theory and gravity theory. John Moffat is also the author of Reinventing Gravity (2008) and Einstein Wrote Back (2010).

Book Synopsis Tau Lepton Physics - Proceedings Of The Second Workshop by : K K Gan
Download or read book Tau Lepton Physics - Proceedings Of The Second Workshop written by K K Gan and published by World Scientific. This book was released on 1993-04-08 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: The II International Workshop on Tau Lepton Physics was held in Ohio, USA in September 1992. Its purpose is to gather the experts on tau lepton physics to examine the current understanding of the tau lepton physics and to assess future prospects. A particular emphasis of the Workshop was a detailed examination of the '1-prong problem': the discrepancy between the inclusive measurement of one-charged-particle decay branching ratio and the sum of the exclusive decays. The Workshop also stimulated new ideas on tests of the Standard Model using the third generation lepton and assessed the future prospects of the lepton physics.
Book Synopsis Handbook of Particle Physics by : M.K. Sundaresan
Download or read book Handbook of Particle Physics written by M.K. Sundaresan and published by CRC Press. This book was released on 2017-12-19 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Literally thousands of elementary particles have been discovered over the last 50 years, their properties measured, relationships systematized, and existence and behavior explained in a myriad of cleverly constructed theories. As the field has grown so impressively, so has its jargon. Until now, scientists in other fields have had no single resource from which they can quickly reference an idea, acronym, or term and find an accessible definition and explanation. The Handbook of Particle Physics fills that void. This unique work contains, in encyclopedic form, terms of interest in particle physics, including its peculiar jargon. It covers the experimental and theoretical techniques of particle physics along with terms from the closely related fields of astrophysics and cosmology. Designed primarily for non-specialists with a basic knowledge of quantum mechanics and relativity, the entries preserve a degree of rigor by providing the relevant technical and mathematical details. Clear and engaging prose, numerous figures, and historical overviews complement the handbook's convenience both as a reference and as an invitation into the fascinating world of particle physics.

Available in PDF, EPUB and Kindle. Book excerpt: This book has three volume. The first volume is mainly devoted to the macroscopic-microscopic theory in its traditional form and extended to very high mass and charge asymmetry. Applications of this theory to the emission of different kinds of charged particles from nuclei are presented in the second volume, where recent experimental achievements in alpha decay, proton, and heavy ion (14C, 24Ne, 28Mg, etc.) radioactivities are also discussed. Experiments on spontaneous fission, fission isomers, and more complex phenomena like particle-accompanied fission,delayed processes: p, a, 2p, t, n, 2n, 3n, and the new mechanism of cold fission (or fission with compact shapes) are described in detail in the third volume.

Book Synopsis Search for the Higgs Boson by : John V. Lee
Download or read book Search for the Higgs Boson written by John V. Lee and published by Nova Publishers. This book was released on 2006 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Higgs boson is an undiscovered elementary particle, thought to be a vital piece of the closely fitting jigsaw of particle physics. Like all particles, it has wave properties akin to those ripples on the surface of a pond which has been disturbed; indeed, only when the ripples travel as a well defined group is it sensible to speak of a particle at all. In quantum language the analogue of the water surface which carries the waves is called a field. Each type of particle has its own corresponding field. The Higgs field is a particularly simple one -- it has the same properties viewed from every direction, and in important respects in indistinguishable from empty space. Thus physicists conceive of the Higgs field being "switched on", pervading all of space and endowing it with "grain" like that of a plank of wood. The direction of the grain in undetectable, and only becomes important once the Higgs' interactions with other particles are taken into account. for instance, particles call vector bosons can travel with the grain, in which case they move easily for large distances and may be observed as photons - that is, particles of light that we can see or record using a camera; or against, in which case their effective range is much shorter, and we call them W or Z particles. These play a central role in the physics of nuclear reactions, such as those occurring in the core of the sun. The Higgs field enables us to view these apparently unrelated phenomenon as two sides of the same coin; both may be described in terms of the properties of the same vector bosons. When particles of matter such as electrons or quarks (elementary constituents of protons and neutrons, which in turn constitute the atomic nucleus) travel through the grain, they are constantly flipped "head-over-heels". this forces them to move more slowly than their natural speed, that of light, by making them heavy.
