Available in PDF, EPUB and Kindle. Book excerpt: A description is given of an experiment performed at the PEP electron-positron storage ring, using the DELCO detector, to measure the formation of charged particle pairs from interactions of pairs of virtual photons radiated from the colliding electron beams. The final states which are measured are electron-positron pairs, charged pion pairs, charged kaon pairs, and proton pairs. Electron-positron pairs are separated from other data by use of gas Cerenkov counters. The shapes of all kinematic distributions are found to agree with predictions of quantum electrodynamics. These data also are used as an accurate normalization for subtraction of the muon-pair background and for measurement of the cross sections of the three hadronic channels. Pion pairs are measured in the mass range from 0.6 to 2.0 GeV, where production of the f (1270) resonance is observed to interfere with significant continuum production. The continuum is well described by single-pion exchange, allowing a measurement of the f two-photon partial width of 3.47 +- 0.37 keV. No a priori assumption is made about the ratio of helicity amplitudes, and the phenomenological model used in fitting the data is constrained to satisfy elastic unitarity. If unitarity is not required, then the fitted partial width is a factor of 0.83 lower than the quoted value. The Q2 dependence of the cross section is found to be consistent with predictions of the Generalized Vector Dominance Model. Kaon pairs and proton pairs are identified by time-of-flight measurements. Kaon pairs are measured in the mass range from 1.3 to 2.0 GeV, where production of the f' (1520) resonance is observed. The ratio of the f and f' two-photon partial widths is found to be consistent with SU(3) quark model predictions with a mixing angle of 28 +- 4 degrees. Twenty-three proton pairs are observed.

Available in PDF, EPUB and Kindle. Book excerpt: This volume reports on all aspects of high energy photon interactions using both photon and proton targets. Significant new results from the LEP and HERA experiments as well as from CLEO II and BELLE are presented. These data are confronted with diverse theoretical models. In particular, predictions of QCD in both the perturbative and the non-perturbative sector are extensively discussed. The prospects for gamma-gamma physics at future high energy colliders are also reviewed. In total 72 papers are collected.The proceedings have been selected for coverage in: ?

Book excerpt: Valerio Filippini devoted his life to physics. His scientific contributions were provided in the OBELIX and FINUDA experiments. The FINUDA experiment collected physics data immediately after the roll-in, thanks to the reliability and simplicity of the on-line system designed and assembled by the physicist. This work is dedicated to him.

Available in PDF, EPUB and Kindle. Book excerpt: We present a new measurement of the cross section for the process ee/sup −/ → e+e/sup /minus//?+?/sup /minus// at center-of-mass energy 29 GeV for invariant pion pair masses M/sub /phi//phi// between 350 MeV/c2 and 3.5 GeV/c2. For M/sub /pi//pi// above 2.1 GeV/c2, we find approximate agreement with the hard-scattering prediction of Brodsky and Lepage. In the low mass region, we observe the f2(1270), and measure its radiative width to be 3.15 /plus minus/ .04 /plus minus/ .39 keV. We also observe an enhancement in the /pi//sup +//pi//sup /minus// spectrum near 1 GeV. We hypothesize that it is the f0(975) and determine it's radiative width to be 0.29 /plus minus/ .07 /plus minus/ .12 keV. 48 refs.

This book was released on 2001-04-10 with total page 2196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of reviews covering all aspects of quantum chromodynamics as we know it today. The articles have been written by recognized experts in this field, in honor of the 75th birthday of Professor Boris Ioffe. Combining features of a handbook and a textbook, this is the most comprehensive source of information on the present status of QCD. It is intended for students as well as physicists — both theorists and experimentalists.Each review is self-contained and pedagogically structured, providing the general formulation of the problem, telling where it stands with respect to other issues and why it is interesting and important, presenting the history of the subject, qualitative insights, and so on. The first part of the book is historical in nature. It includes, among other articles, Boris Ioffe's and Yuri Orlov's memoirs on high energy physics in the 1950's, a note by B V Geshkenbein on Ioffe's career in particle physics, and an essay on the discovery of asymptotic freedom written by David Gross.
