Available in PDF, EPUB and Kindle. Book excerpt: The search for signals from Supersymmetry at hadron colliders has largely been centered on the search for squark and gluino production, usually through events with large missing transverse energy (E{sub t}). A promising alternative at the Tevatron is the search for production of the lightest chargino ({tilde W}1) and next-to-lightest neutralino ({tilde Z}2), with the assumptions that R-parity is conserved and the lightest neutralino ({tilde Z}1) is the lightest supersymmetric particle (LSP). Although the mass limit established by LEP experiments, 2M{sub {tilde W}1}>45 GeV/c2, excludes the on-shell process {anti p}p 2!W{sup {+-}} 2!{tilde W}1 + {tilde Z}2, the off-shell process W{sup {+-}} 2!{tilde W}1{tilde Z}2 can have a sizeable rate due to large WW{tilde W}1{tilde Z}2 coupling. Here, the status of a search for the pair production of the lightest chargino and second lightest neutralino states of the minimal supersymmetric model is presented. The authors searched for four tri-lepton final states: eee, ee[mu], e[mu][mu], and [mu][mu][mu], all with missing transverse energy.

Download or read book An Introduction To Quantum Field Theory written by Michael E. Peskin and published by CRC Press. This book was released on 2018-05-04 with total page 866 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.

Available in PDF, EPUB and Kindle. Book excerpt: The functions studied in this monogra9h are a cross between elliptic functions and modular forms in one variable.

If m= 0, then cp is independent of z and the definition reduces to the usual notion of modular forms in one variable. We give three other examples of situations where functions satisfying (1)-(3) arise classically: 1. Theta series. Let Q: ~-+ ~ be a positive definite integer valued quadratic form and B the associated bilinear form.
Download or read book Perspectives on Supersymmetry II written by G. L. Kane and published by World Scientific. This book was released on 2010 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supersymmetry is at an exciting stage of development. It extends the Standard Model of particle physics into a more powerful theory that both explains more and allows more questions to be addressed. Most importantly, it opens a window for studying and testing fundamental theories at the Planck scale. Experimentally we are finally entering the intensity and energy and sensitivity regions where superpartners and supersymmetric dark matter candidates are likely to be detected, and then studied. There has been progress in understanding the remarkable physics implications of supersymmetry, including the derivation of the Higgs mechanism, the unification of the Standard Model forces, cosmological connections such as a candidate for the cold dark matter of the universe and consequences for understanding the cosmological history of the universe, and more. This volume begins with an excellent pedagogical introduction to the physics and methods and formalism of supersymmetry which is accessible to anyone with a basic knowledge of the Standard Model of particle physics.Next is an overview of open questions, followed by chapters on topics such as how to detect superpartners and tools for studying them, the current limits on superpartner masses as we enter the LHC era, the lightest superpartner as a dark matter candidate in thermal and non-thermal cosmological histories, and associated Z'' physics. Most chapters have been extended and updated from the earlier edition and some are new. This superb book will allow interested physicists to understand the coming experimental and theoretical progress in supersymmetry and the implications of discoveries of superpartners, and will also help students and workers to quickly learn new aspects of supersymmetry they want to pursue.
Download or read book Neutrino Physics written by E. Bellotti and published by IOS Press. This book was released on 2003-12-08 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrino physics contributed in an fundamental way to the progress of science, opening important windows of knowledge in elementary particle physics, as well in astrophysics and cosmology. Substantial experimental efforts are presently dedicated to improve our knowledge on neutrino properties as, in fact, we don't know yet some of the basic ones. Although very significant steps forward have been done, neutrino masses and mixings still remain largely unknown and constitute an important field for future research. Are neutrinos Majorana or Dirac particles? Have they a magnetic moment? Historically, studies on weak processes and, therefore, on neutrino physics, provided first the Fermi theory of weak interactions and then the V-A theory. Finally, the observation of weak neutral currents provided the first experimental evidence for unification of weak and electromagnetic interactions by the so called "Standard Model' of elementary particles. In addition to the results obtained from the measurement of the solar neutrino flux, the study of atmospheric neutrinos strongly supports the hypothesis of neutrino oscillation among different flavours. At the same time, the detection of neutrinos emitted by our Sun gave an important confirmation that the Sun produces energy via a chain of nuclear reactions; in particular in our Sun a specific cycle - the hydrogen cycle - is responsible for practically all the produced energy.

Book excerpt: Torn Between Two Lovers, Feeling Like A Fool Abby Stafford, new Alpha of the Hat Island Pack, has a lot to deal with. The serum the Hat Island Pack has developed will save the lives of shifter girls everywhere -- and change the world forever -- if the Pack can survive long enough to get it into production. And she's been a wolf for all of a month. She's in love with her Second in command. And they're scrambling to make a real shifter community on Hat Island, hopefully with some income-producing businesses. Income would be good. Really good. But someone is gunning for the pack -- trying to stop the serum, trying to prevent Abby from being Alpha. In the last month there have been seven attempts on her life. Then someone makes a run at the Tanaka pack Alpha in Seattle -- and the only way to save his life is through a mate bond. Abby knows realistically that Hat Island won't last two weeks with Akihiro Tanaka's support and backing. And she's aware of her own growing feelings for the man. Why wouldn't she want him? He was urbane, polished, intelligent.... But she loves Jake, her Second. Jake says she doesn't have to choose. She can have both. She doubts it's as simple as that, but there's not much time, and very little choice. So another new thing in the shifter world: two alphas mated. She hopes they all survive it. Book 2 in the new urban adventure series, Wolf Harbor, a feminist werewolf story.

Download or read book Modern Supersymmetry written by John Terning and published by OUP Oxford. This book was released on 2009-01-15 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book begins with a brief review of supersymmetry, and the construction of the minimal supersymmetric standard model and approaches to supersymmetry breaking. General non-perturbative methods are also reviewed leading to the development of holomorphy and the Affleck-Dine-Seiberg superpotential as powerful tools for analysing supersymmetric theories. Seiberg duality is discussed in detail, with many example applications provided, with special attention paid to its use in understanding dynamical supersysmmetry breaking. The Seiberg-Witten theory of monopoles is introduced through the analysis of simpler N=1 analogues. Superconformal field theories are described along with the most recent development known as "amaximization". Supergravity theories are examined in 4, 10, and 11 dimensions, allowing for a discussion of anomaly and gaugino mediation, and setting the stage for the anti- de Sitter/conformal field theory correspondence. This book is unique in containing an overview of the important developments in supersymmetry since the publication of "Suppersymmetry and Supergravity" by Wess and Bagger. It also strives to cover topics that are of interest to both formal and phenomenological theorists.
