This book was released on 2005 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have studied the 3P{sub J} ([chi]{sub e}) states of charmonium in formation by antiproton-proton annihilations in experiment E835 at the Fermilab Antiproton Source. The authors report new measurements of the mass, width, and B([chi]{sub cJ} 2!{bar p}p) x [Lambda]([chi]{sub eJ} 2!J/[psi] + anything) for the [chi]{sub c1} and [chi]{sub c2} by means of the inclusive reaction {bar p}p 2![chi]{sub cJ} 2!J/[psi] + anything 2!(ee−) + anything. Using the subsample of events where [chi]{sub cJ} 2![gamma] + J/[psi] 2![gamma] + (e+e−) is fully reconstructed, we derive B([chi]{sub cJ} 2!{bar p}p) x [Lambda]([chi]{sub cJ} 2!J/[psi] + [gamma]). They summarize the results of the E760 (updated) and E835 measurements of mass, width and B([chi]{sub cJ} 2!{bar p}p)[Lambda]([chi]{sub cJ} 2!J/[psi] + [gamma]) (J = 0,1,2) and discuss the significance of these measurements.

Available in PDF, EPUB and Kindle. Book excerpt: The authors report on a study of the[sup 3]P[sub 1]([chi][sub 1]) and[sup 3]P[sub 2]([chi][sub 2]) states of charmonium formed in antiproton-proton annihilations. An energy scan through the resonances, performed with a very narrow momentum-band beam of antiprotons intersecting a hydrogen jet target, enables them to perform very precise measurements of the mass and the total width of the two resonances. From their measurement of the quantity[Gamma](R[r-arrow][anti p]p)[times] BR(R[r-arrow] J/[psi][gamma])[times] BR(J[psi][r-arrow] e[sup+]e[sup[minus]]), using known branching ratios, the authors obtain:[Gamma]([chi][sub 1][r-arrow][anti p]p)= (69[+-] 13) eV;[Gamma]([chi][sub 2][r-arrow][anti p]p)= (180[+-] 31) eV.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The 90% confidence upper limits for the decay channels studied in the mass range 3525.1--3527.3 MeV for a 1P 1 resonance with a presumed width of 1.0 MeV were determined to be B(pp¯ → 1P 1) x B(1P 1 → J/psi + X) ≤ 1.8 x 10-7, B(pp¯ → 1P1) x B( 1P1 → J/psi + pi 0) ≤ 1.2 x 10-7, and B( pp¯ → 1P1) → B(1P1 → J/psigamma) ≤ 1.0 x 10-7. No evidence for a 1P1 enhancement was observed in either of the two additional reactions studied; pp¯ → J/psi + pi0pi0 → e+e- + 4gamma and pp¯ → etacgamma → (gammagamma)gamma.

Book excerpt: The two-volume set Lectures on QCD provides an introductory overview of Quantum Chromodynamics, the theory of strong interactions. In a series of pedagogically written articles based on lectures given over the years to graduate students, the fundamentals of QCD are discussed and significant application areas are described. The field-theoretic basis of QCD is the focus of the first volume, while the application of QCD to the phenomenology of strong interactions forms the subject of the second volume.
Download or read book Particle Physics written by Brian R. Martin and published by John Wiley & Sons. This book was released on 2013-03-22 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: An essential introduction to particle physics, with coverage ranging from the basics through to the very latest developments, in an accessible and carefully structured text. Particle Physics: Third Edition is a revision of a highly regarded introduction to particle physics. In its two previous editions this book has proved to be an accessible and balanced introduction to modern particle physics, suitable for those students needed a more comprehensive introduction to the subject than provided by the ‘compendium’ style physics books. In the Third Edition the standard model of particle physics is carefully developed whilst unnecessary mathematical formalism is avoided where possible. Emphasis is placed on the interpretation of experimental data in terms of the basic properties of quarks and leptons. One of the major developments of the past decade has been the establishing of the existence of neutrino oscillations. This will have a profound effect on the plans of experimentalists. This latest edition brings the text fully up-to-date, and includes new sections on neutrino physics, as well as expanded coverage of detectors, such as the LHC detector. End of chapter problems with a full set of hints for their solutions provided at the end of the book. An accessible and carefully structured introduction to this demanding subject. Includes more advanced material in optional ‘starred’ sections. Coverage of the foundations of the subject, as well as the very latest developments.
Download or read book The Physics of the Quark Gluon Plasma written by Sourav Sarkar and published by Springer Science & Business Media. This book was released on 2009-12-16 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to offer to the next generation of young researchers a broad and largely self-contained introduction to the physics of heavy ion collisions and the quark-gluon plasma, providing material beyond that normally found in the available textbooks. For each of the main aspects - QCD thermodynamics and global features of the QGP, collision hydrodynamics, electromagnetic probes, jet and quarkonium production, color glass condensate, and the gravity connection - the present volume provides extensive and pedagogical lectures, surveying the present status of both theory and experiment. A particular feature of this volume is that all lectures have been written with the active assistance of selected students present at the course in order to ensure the adequate level and coverage for the intended readership.
Download or read book Ultrarelativistic Heavy Ion Collisions written by Ramona Vogt and published by Elsevier. This book was released on 2007-06-04 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed for advanced undergraduate and graduate students in high energy heavy-ion physics. It is relevant for students who will work on topics being explored at RHIC and the LHC. In the first part, the basic principles of these studies are covered including kinematics, cross sections (including the quark model and parton distribution functions), the geometry of nuclear collisions, thermodynamics, hydrodynamics and relevant aspects of lattice gauge theory at finite temperature. The second part covers some more specific probes of heavy-ion collisions at these energies: high mass thermal dileptons, quarkonium and hadronization. The second part also serves as extended examples of concepts learned in the previous part. Both parts contain examples in the text as well as exercises at the end of each chapter. - Designed for students and newcomers to the field- Focuses on hard probes and QCD- Covers all aspects of high energy heavy-ion physics- Includes worked example problems and exercises
Download or read book Particle Physics Reference Library written by Herwig Schopper and published by Springer Nature. This book was released on 2020 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access
Download or read book The Hydrogen Atom written by G. Franco Bassani and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic hydrogen, the simplest of all stable atoms, has been a challenge to spectroscopists and theoreticians for many years. Here, as in similar systems like positronium, muonium and possibly helium, the accuracy of theoretical predictions is comparable to that of experimental measurements. Hence exciting confrontations are possible. This together with expected large experimental improvements explains the strong interest in the symposium held in Pisa in June-July 1988. The resulting book completely covers the precision spectroscopy of atomic hydrogen and hydrogen-like systems, and also discusses aspects of QED and the influence of strong fields.
