Book excerpt: The $1/N_c$ expansion of QCD provides a useful framework for phenomenological studies of both ground state and excited baryons. Here, we focus on its application to the excited baryon strong decays via emission of single pseudoscalar meson. The S- and D-wave decay amplitudes of the negative parity baryons in the $[70,1^-]$ of $SU(6)$ are analyzed to subleading order in $1/N_c$ and to first order in SU(3) symmetry breaking. In particular, the SU(3) symmetry breaking is studied in detail through SU(3) breaking decay operators and state mixing.
Book Synopsis Decays of Negative Parity Non-strange Baryons in the 1/Nc Expansion by :
Download or read book Decays of Negative Parity Non-strange Baryons in the 1/Nc Expansion written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The decays of non-strange negative parity baryons via the emission of single [pi] and [eta] mesons are analyzed in the framework of the 1/N{sub c} expansion. A basis of spin-flavor operators is established to that order, and with this basis the different partial wave decay amplitudes are obtained. The unknown effective coefficients are determined by fitting to the S- and D-wave partial widths as provided by the PDG. A full set of relations between widths that result at the leading order, i.e. order N{sub c0}, is given and tested with the data. The rather large errors of the input partial widths, that result from the often discrepant results for the resonance parameters from different analyses of the data, lead to a rather good fit at the leading order N{sub c0}. The next to leading order fit fails for that reason to pin down with satisfactory accuracy the effective sub leading effective constants.
Book Synopsis Phenomenology of Large Nc QCD by : Richard F. Lebed
Download or read book Phenomenology of Large Nc QCD written by Richard F. Lebed and published by World Scientific. This book was released on 2002 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generalization of QCD from three to N C colors, developed in 1974 by Nobel laureate Gerard ''t Hooft, has proved to be an extraordinarily useful and robust theoretical extension for studying the behavior of strong interaction physics. This book is the proceedings of the first-ever meeting exclusively devoted to large N C QCD. The workshop brought together representatives of many subdisciplines for a OC meeting of mindsOCO on topics ranging from finite temperature and density to the lattice, perturbative QCD, instantons, mesons, baryons, and nuclear physics. Beginning with ''t Hooft''s keynote presentation, the contributions are designed to introduce uses of large N C methods in each specialty to a broader particle physics audience."

Book Synopsis Large Nc Qcd 2004 - Proceedings Of The Workshop by : Jose Luis Goity
Download or read book Large Nc Qcd 2004 - Proceedings Of The Workshop written by Jose Luis Goity and published by World Scientific. This book was released on 2005-08-04 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large Nc limit plays a fundamental role in the study of non-abelian gauge theories such as quantum chromodynamics (QCD). Since its discovery in 1974 by 't Hooft, the 1/Nc expansion has provided crucial insights into the non-perturbative aspects of gauge theories. The expansion implemented at the effective theory level is one of the fundamental tools currently in use in hadronic physics; there are important effects and relations that follow from the 1/Nc expansion, which held remarkably well in the real world with Nc= 3. The 1/Ncexpansion also plays a central role in the recently discovered connections between non-Abelian gauge and string theories, promising new ways to analyze the non-perturbative domain of gauge theories.This volume contains contributions from leading theorists and covers the recent developments in the 1/Nc expansion in QCD. The topics addressed include confinement, AdS/CFT correspondence and the string-QCD connection, topology in large Nc, lattice QCD, and a variety of applications to mesons and baryons.
Book Synopsis Excited Nucleons and Hadronic Structure by : V. Burkert
Download or read book Excited Nucleons and Hadronic Structure written by V. Burkert and published by World Scientific. This book was released on 2001 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conference NSTAR 2000 was part of a series of conferences and workshops that began in New York in 1988. Since then, the field of excited nucleons and hadron structure has developed enormously, and the scope has broadened. Most significantly, new experimental facilities have come into operation, allowing precise measurements of resonance couplings and transition form factors. The search for ?missing? quark model states and gluonic excitations in complex hadronic channels is now possible.On the theory side, new and promising developments have emerged: quark models with meson degrees of freedom, hybrid baryon models, and studies of baryons in the limit of many colors. For the first time, lattice QCD has been employed to calculate masses of excited nucleons. Nucleon resonances are now recognized as providing significant contributions to the nucleon spin sum rules, as well as the Gerasimov-Drell-Hearn and Bjorken integrals, at finite momentum transfer.

Download or read book Particle Physics: Perspectives And Opportunities - Report Of The Dpf Committee On Long-term Planning written by Robert N Cahn and published by World Scientific. This book was released on 1995-09-20 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of a broad-based and in-depth study of high energy physics commissioned by the Executive Committee of the Division of Particles and Fields of the American Physical Society. This year-long study was initiated in the early 1994, in the wake of the cancellation of the SSC, and is meant to complement the report of the Drell HEPAP subpanel, charged with providing a vision for the future of the field. The DPF study of high energy physics was organized on the basis of the working groups, each led by a number of co-conveners chosen among established leaders in the various subspecialties in the field. These conveners, in turn, organized their working groups by inviting other active workers in the discipline to participate and gathered further input from the community by holding a variety of specialized meetings and workshops. This book contains the final reports of the 11 working groups assembled for the study, along with an extended overview and executive summary by the editors.
