Book Multiplicities in High Energy Interactions

Download or read book Multiplicities in High Energy Interactions written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Charged particle multiplicities in hadronic collision have been measured for all energies up to .sqrt.s = 540 GeV in the center of mass. Similar measurements in ee− annihilation cover the much smaller range - up to .sqrt.s = 40 GeV. Data are also available from deep inelastic neutrino scattering up to .sqrt.s approx. 10 GeV. The experiments measure the mean charged multiplicity , the rapidity density at y = O, and the distributions in prong number. The mean number of photons associated with the events can be used to measure the .pi.° and eta° multiplicities. Some information is also available on the charged pion, kaon, and nucleon fractions as well as the K° and .lambda.° rates and for the higher energy data, the identically equal fraction. We review this data and consider the implications of extrapolations to SSC energies. 13 references.

Book Measurement of Charged Particle Multiplicities in Gluon and Quark Jets in Proton Anti proton Collisions at S

Download or read book Measurement of Charged Particle Multiplicities in Gluon and Quark Jets in Proton Anti proton Collisions at S written by and published by . This book was released on 2004 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report the first model independent measurement of charged particle multiplicities in quark and gluon jets, N{sub q} and N{sub g}, produced at the Tevatron in p{bar p} collisions with center-of-mass energy 1.8 TeV and recorded by the Collider Detector at Fermilab. The measurements are made for jets with average energies 41 and 53 GeV by counting charged particle tracks in cones with opening angle of?{sub c} = 0.28, 0.36, and 0.47 rad around the jet axis. The corresponding jet hardness Q = E{sub jet}?{sub c} varies in the range from 12 GeV to 25 GeV. At Q = 19 GeV, the ratio of multiplicities r = N{sub g}/N{sub q} is found to be 1.64 ± 0.17, where statistical and systematic uncertainties are added in quadrature. The results are in agreement with re-summed perturbative QCD calculations.
