Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this paper is to review progress in the US towards a next generation linear collider. During 1988, there were three workshops held on linear colliders: Physics of Linear Colliders, '' in Capri, Italy, June 14--18, 1988; Snowmass 88 (Linear Collider subsection) June 27--July 15, 1988; and SLAC International Workshop on Next Generation Linear Colliders, November 28--December 9, 1988. In this paper, I focus on reviewing the issues and progress on a next generation linear collider. The energy range is dictated by physics with a mass reach well beyond LEP, although somewhat short of SSC. The luminosity is that required to obtain 103--104 units of R0 per year. The length is consistent with a site on Stanford land with collision occurring on the SLAC site; the power was determined by economic considerations. Finally, the technology as limited by the desire to have a next generation linear collider by the next century. 37 refs., 3 figs., 6 tabs.

Book excerpt: The present thinking on high-energy e/sup /plus//e/sup /minus// linear colliders is reviewed, stressing those points that have consequences for detector design and physics analyses. Detector requirements are discussed. Experimental aspects of the physics that can be done at these colliders are discussed: first the general physics environment, then a standard process, W/sup /plus// W/sup /minus// detection, and finally four examples of the discovery potential of these colliders -- heavy quarks, heavy leptons, standard Higgs bosons, and charged Higgs bosons.

Book excerpt: The authors present the prospects for the next generation of high-energy physics experiments with electron-positron colliding beams. This report summarizes the current status of the design and technological basis of a linear collider of center-of-mass energy 0.5--1.5 TeV, and the opportunities for high-energy physics experiments that this machine is expected to open. The physics goals discussed here are: Standard Model processes and simulation; top quark physics; Higgs boson searches and properties; supersymmetry; anomalous gauge boson couplings; strong WW scattering; new gauge bosons and exotic particles; e[sup[minus]]e[sup[minus]], e[sup[minus]][gamma], and[gamma][gamma] interactions; and precision tests of QCD.
Download or read book Attaining High Luminosity in Linear E Sup E Sup Minus Colliders written by and published by . This book was released on 1990 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The attainment of high luminosity in linear colliders is a complex problem because of the interdependence of the critical parameters. For instance, changing the number of particles per bunch affects the damping ring design and thus the emittance; it affects the wakefields in the linac and thus the momentum spread; the momentum spread affects the final focus design and thus the final [beta]*; but the emittance change also affects the final focus design; and all these come together to determine the luminosity, disruption and beamstrahlung at the intersection. Changing the bunch length, or almost any other parameter, has a similar chain reaction. Dealing with this problem by simple scaling laws is very difficult because one does not know which parameter is going to be critical, and thus which should be held constant. One can only maximize the luminosity by a process of search and iteration. The process can be facilitated with the aid of a computer program. Examples can then be optimized for maximum luminosity, and compared to the optimized solutions with different approaches. This paper discusses these approaches.

Book excerpt: In the framework of the discussion on what shape the future machine arsenal should take so as to maximize the chances of penetrating beyond the realm where the present astonishingly successful Standard Model of Particle Interactions holds undisputed sway, the present contribution is somewhat unusual: the author is not here to convince the community to build yet another machine. Instead, his task is to convince you that in the established choices that the accelerator community is headed towards, it is of great importance that the Electron Collider of the next generation, i.e., in the 0.5 to 1.5 TeV energy range, should be configured just such, as an Electron collider, NOT dedicated to just one incoming charge state (say, e[sup+]e[sup[minus]]). Now that the energy range that can be reached with circular/recirculating machines has been exceeded, designers are freed from the need to have oppositely charged electrons as projectiles and targets. The colliding linac configuration sets no preferential condition on the chosen net charge; in fact, this is the first time such a machine may well serve to collide a variety of initial states at full energy 2E[sub B] and luminosity (e[sup+]e[sup+], e[sup+]e[sup[minus]], e[sup[minus]]e[sup[minus]]), or at slightly reduced center-of-mass energy, but still full luminosity ([gamma]-e, [gamma]-[gamma]).

Book excerpt: Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors point out that the ratio of W[sup+]W[sup[minus]][yields] W[sup+]W[sup[minus]] and W[sup+]W[sup[minus]][yields] ZZ cross sections is a sensitive probe of the dynamics of electroweak symmetry breaking, in the CM energy region[radical]s[sub ww][approx-gt] 1 TeV where vector boson scattering may well become strong. They suggest ways in which this ratio can be extracted at a 1.5 TeV e[sup+]e[sup[minus]] linear collider, using W[sup[+-]], Z[yields] jj hadronic decays and relying on dijet mass resolution to provide statistical discrimination between W[sup[+-]] and Z. WW fusion processes studied here are unique for exploring scalar resonances of mass about 1 TeV and are complementary to studies via the direct channel e[sup+]e[sup[minus]][yields] W[sup+]W[sup[minus]] for the vector and non-resonant cases. With an integrated luminosity of 200 fb[sup[minus]1], the signals obtained are statistically significant. Comparison with a study of e[sup[minus]]e[sup[minus]][yields][nu][nu]W[sup[minus]]W[sup[minus]] process is made. Enhancements of the signal rate from using a polarized electron beam, or at a 2 TeV e[sup+]e[sup[minus]] linear collider and possible higher energy[mu][sup+][mu][sup[minus]] colliders, are also presented.

Book excerpt: A survey is presented of the physics opportunities at TeV ee− linear colliders. Examples are given of physics that might emerge in e+e− collisions and in?? collisions using the back-scattered laser technique, including?? 2!ZZ scattering as a probe of ultraheavy quanta. The second portion of the talk focuses on physics that must emerge at or below the TeV scale--the mechanism of electroweak symmetry breaking. In particular a very rough estimate is presented of the most challenging possible signal of symmetry breaking, strong WW scattering, as a function of collider energy. A subtheme, made explicit in the concluding section, is the continuing complementarity of e+e− and pp colliders in the domain of TeV physics.

Available in PDF, EPUB and Kindle. Book excerpt: Recent studies concerning optimization parameters for ee− super linear colliders use multiple particle bunches for each rf pulse to increase the luminosity and overall efficiency. Requirements for final focusing of the beams severely restrict the bunch to bunch energy variation during the rf pulse. To accurately determine the accelerating fields and energy variation, the dispersion related transient behavior of the rf drive pulse must be considered. A numerical study of dispersion effects on several different accelerating structures is presented.
