Available in PDF, EPUB and Kindle. Book excerpt: The interaction potential V(Q[sup 2]) between static test charges can be used to define an effective charge[alpha][sub V](Q[sup 2]) and a physically-based renormalization scheme for quantum chromodynamics and other gauge theories. In this paper we use recent results for the finite-mass fermionic corrections to the heavy-quark potential at two-loops to derive the next-to-leading order term for the Gell Mann-Low function of the V-scheme. The resulting effective number of flavors N[sub F](Q[sup 2]/m[sup 2]) in the[alpha][sub V] scheme is determined as a gauge-independent and analytic function of the ratio of the momentum transfer to the quark pole mass. The results give automatic decoupling of heavy quarks and are independent of the renormalization procedure. Commensurate scale relations then provide the next-to-leading order connection between all perturbatively calculable observables to the analytic and gauge-invariant[alpha][sub V] scheme without any scale ambiguity and a well defined number of active flavors. The inclusion of the finite quark mass effects in the running of the coupling is compared with the standard treatment of finite quark mass effects in the[ovr MS] scheme.
Download or read book Particle Production Spanning MeV and TeV Energies written by W. Kittel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle production is an important topic in nuclear and particle physics. At high energies, particle production is considered to proceed via parton branching and subsequent fragmentation into hadrons. The study of the dynamics of this process and the study of the structure of hadrons in the context of quantum chromodynamics (QCD) belong to the challenges of the standard model of elementary particle physics, requiring new, nonperturba tive approaches in field theory. Within a nucleus, many-body dynamics is important and particle production may be used to determine many features of a non-equilibrium quantum system at low or high temperatures. At this Advanced Study Institute the different aspects of particle pro duction were expanded upon in a series of lectures given by experts in their fields, covering topics ranging from near-threshold meson production in proton-proton collisions to correlations in multi-GeV jet fragmentation in high-energy scattering processes and signals of a quark-gluon plasma formed in ultra-relativistic heavy-ion collisions. Strong emphasis was placed not only on state of the art research, but also on the necessary physics back ground. The lectures were supplemented by problem sets and discussion sessions. There was also time for students to present short contributions on their research.

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 Hadron Mass Spectrum written by E. Klempt and published by Elsevier. This book was released on 2016-06-03 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hadron Mass Spectrum covers the proceedings of the Rheinfels Workshop on the Hadron Mass Spectrum, held in St. Goar, Germany on September 3-6, 1990. The book focuses on the processes, methodologies, and reactions involved in hadron spectroscopy. The selection first offers information on strange meson and strangeonium spectroscopy and strangeonium production from LASS. The book also takes a look at the status of strange meson spectroscopy, including status of the spectroscopy, systematics of the level structure, and contributions from LASS. The publication examines the scalar meson enigma and two photon couplings of scalar and tensor mesons. The manuscript also touches on rhoprimes, omegaprimes, and glueballs; meson production mechanisms and selection criteria for cryptoexotic states; and light meson spectroscopy and threshold effects. The selection is a dependable reference for readers interested in hadron mass spectrum.

Available in PDF, EPUB and Kindle. Book excerpt: Particle and nuclear physicists frequently take results from Lattice QCD at their face value without probing into their reliability or sophistication. This attitude usually stems from a lack of knowledge of the field. The aim of the present volume is to rectify this by introducing in an elementary way several topics, which we believe are appropriate for, and of possible interest to, both particle and nuclear physicists who are non-experts in the field.

Download or read book The Deconfinement Transition of QCD written by Claudia Ratti and published by Springer Nature. This book was released on 2021-06-14 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years, numerical simulations of QCD on the lattice have reached a new level of accuracy. A wide range of thermodynamic quantities is now available in the continuum limit and for physical quark masses. This allows a comparison with measurements from heavy ion collisions for the first time. Furthermore, calculations of dynamical quantities are also becoming available. The combined effort from first principles and experiment allows to gain an unprecedented understanding of the properties of quark-gluon plasma. This concise text, geared towards postgraduate students and newcomers to the field, carefully introduces and reviews the state-of-the-art techniques and results from lattice simulations and connects them to the experimental information from RHIC and the LHC.

Download or read book On the Two loop Virtual QCD Corrections to Higgs Boson Pair Production in the Standard Model written by and published by . This book was released on 2016 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here, we compute the next-to-leading order virtual QCD corrections to Higgs-pair production via gluon fusion. We also present analytic results for the two-loop contributions to the spin-0 and spin-2 form factors in the amplitude. The reducible contributions, given by the double-triangle diagrams, are evaluated exactly while the two-loop irreducible diagrams are evaluated by an asymptotic expansion in heavy top-quark mass up to and including terms of O(1/m$8\atop{t}$). We estimate that mass effects can reduce the hadronic cross section by at most 10 %, assuming that the finite top-quark mass effects are of similar size in the entire range of partonic energies.
