Описание: Physicists actively engaged in advanced research should be en- couraged to discuss results and deepen their theoretical understand- ing of the data. It is practically impossible nowadays to achieve the goal of the old times when small groups of scientists had the privilege of debating their ideas and the details of their experi- ments in an informal and friendly way. Conferences are now too wide in scientific coverage and, in consequence, there are often too many participants. The Highly Specialized Seminars of the Ettore Majorana Centre for Scientific Culture are intended to provide such a forum for scientists of outstanding reputation in their fields to exchange information. This volume deals with one of the most interesting topics in subnuclear physics, and Professor Giuliano Preparata is one of the world's leaders in the field. This volume contains the most recent results on the study of deep inelastic phenomena, using neutrinos, muons and electrons against nucleons, and (e+e-) interactions. It represents our best knowledge of the field as given by some of the most distinguished world experts in the theoretical and experimental domain. Antonino Zichichi, Director Ettore Majorana Centre for Scientific Culture v PREFACE In March 1979, about 50 physicists gathered in Erice to parti- cipate in the Fourth Highly Specialized Seminar on "Probing Hadrons with Leptons."

Описание: Novel forms of matter, such as states made of gluons (glueballs), multiquark mesons or baryons and hybrid mesons are predicted by low energy QCD, for which several candidates have recently been identified. Searching for such exotic states of matter and studying their production and decay properties in detail has become a flourishing field at the experimental facilities now available or being built - e.g. BESIII in Beijing, BELLE II at SuperKEKB, GlueX at Jefferson Lab, PANDA at FAIR, J-PARC and in the upgraded LHC experiments, in particular LHCb. A modern primer in the field is required so as to both revive and update the teaching of a new generation of researchers in the field of QCD. These lectures on hadron spectroscopy are intended for Master and PhD students and have been originally developed for a course delivered at the Stefan Meyer Institute of the Austrian Academy of Sciences. They are phenomenologically oriented and intended as complementary material for basic courses in particle and nuclear physics. The book describes the spectra of light and heavy mesons and baryons, and introduces the fundamental properties based on symmetries. Further, it derives multiplet structures, mixing angle, decay coupling constants, magnetic moments of baryons, and predictions for multiquark states and compares these with suitable experimental data. Basic methods of calculating decay angular distributions and determining masses and widths of resonances are also presented. The appendices provide students and newcomers to the field with the necessary background information, and include a set of problems and solutions.
Описание: Since The Discovery Of Neutrino Oscillations Neutrino Physics Has Become An Interesting Field Of Research In Physics. They Imply That Neutrino Must Have A Small Mass And That The Neutrinos, Coupled To The Charged Leptons, Are Mixtures Of The Mass Eigenstates, Analogous To The Flavor Mixing Of The Quarks. The Mixing Angles For The Quarks Are Small, But For The Leptons Two Of The Mixing Angles Are Large. The Masses Of The Three Neutrinos Must Be Very Small, Less Than 1 Ev, But From The Oscillation Experiments We Only Know The Mass Differences — The Absolute Masses Are Still Unknown. Also We Do Not Know, If The Masses Of The Neutrinos Are Dirac Masses, As The Masses Of The Charged Leptons And Of The Quarks, Or Whether They Are Majorana Masses.In This Volume, An Overview Of The Present State Of Research In Neutrino Physics Is Given By Well-Known Experimentalists And Theorists. The Contents — Originated From Talks And Discussions At A Recent Conference Addressing Some Of The Most Pressing Open Questions In Neutrino Physics — Range From The Oscillation Experiments To Cp-Violation For Leptons, To Texture Zero Mass Matrices And To The Role Of Neutrinos In Astrophysics And Cosmology.
This book shows how the study of multi-hadron production phenomena in the years after the founding of CERN culminated in Hagedorn's pioneering idea of limiting temperature, leading on to the discovery of the quark-gluon plasma -- announced, in February 2000 at CERN.
Following the foreword by Herwig Schopper -- the Director General (1981-1988) of CERN at the key historical juncture -- the first part is a tribute to Rolf Hagedorn (1919-2003) and includes contributions by contemporary friends and colleagues, and those who were most touched by Hagedorn: Tamбs Birу, Igor Dremin, Torleif Ericson, Marek Gaździcki, Mark Gorenstein, Hans Gutbrod, Maurice Jacob, Istvбn Montvay, Berndt Mьller, Grazyna Odyniec, Emanuele Quercigh, Krzysztof Redlich, Helmut Satz, Luigi Sertorio, Ludwik Turko, and Gabriele Veneziano.
The second and third parts retrace 20 years of developments that after discovery of the Hagedorn temperature in 1964 led to its recognition as the melting point of hadrons into boiling quarks, and to the rise of the experimental relativistic heavy ion collision program. These parts contain previously unpublished material authored by Hagedorn and Rafelski: conference retrospectives, research notes, workshop reports, in some instances abbreviated to avoid duplication of material, and rounded off with the editor's explanatory notes.
About the editor:
Johann Rafelski is a theoretical physicist working at The University of Arizona in Tucson, USA. Bor
n in 1950 in Krakow, Poland, he received his Ph.D. with Walter Greiner in Frankfurt, Germany in 1973. Rafelski arrived at CERN in 1977, where in a joint effort with Hagedorn he contributed greatly to the establishment of the relativistic heavy ion collision, and quark-gluon plasma research fields. Moving on, with stops in Frankfurt and Cape Town, to Arizona, he invented and developed the strangeness quark flavor as the signature of quark-gluon plasma.

Описание: This book offers an elementary introduction to hadronic properties at finite temperature and density for graduate students and researchers. Developing real-time methods of thermal field theory, this self-contained text examines the applications of these to thermal properties of hadrons, including heavy ion collisions and transport processes.

Описание: This thesis presents a search for long-lived particles decaying into displaced electrons and/or muons with large impact parameters. This signature provides unique sensitivity to the production of theoretical lepton-partners, sleptons. These particles are a feature of supersymmetric theories, which seek to address unanswered questions in nature. The signature searched for in this thesis is difficult to identify, and in fact, this is the first time it has been probed at the Large Hadron Collider (LHC). It covers a long-standing gap in coverage of possible new physics signatures. This thesis describes the special reconstruction and identification algorithms used to select leptons with large impact parameters and the details of the background estimation. The results are consistent with background, so limits on slepton masses and lifetimes in this model are calculated at 95% CL, drastically improving on the previous best limits from the Large Electron Positron Collider (LEP).
