Available in PDF, EPUB and Kindle. Book excerpt: Interactions of 209-GeV muons in the Multimuon Spectrometer at Fermilab have yielded 20072 dimuon final states, with (81±10)% attributed to production of charmed states decaying to muons. The cross section for diffractive charm muoproduction is 6.9{sub -1.4}{sup +1.9} nb. Extrapolated to Q2 =0, the effective cross section for 178(100)-GeV photons is 750{sup +180}130 (560{sup +200}−130) nb, too small to explain the high-energy rise in the photon-nucleon total cross section.

This book was released on 1994-08-31 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This seminar focusses on the key issues addressed in measuring the hyperon-nucleon strong and weak interaction observables and in modelling the hyperon-nucleon interaction. Both quark and baryon pictures are addressed. Results from recent experiments at BNL, KEK, CERN and FNAL, including hyperon production, polarization and decay, are explored; both S = -1 and S = -2 systems are included. The status of our understanding of hyperon weak decays in the nuclear medium is examined and the constraints placed upon our modelling of the hyperon-nucleon interaction by our knowledge of hypernuclear properties are also investigated. Finally, the present status of, as well as future prospects for, the measurements of the hyperon-nucleon interaction are summarized.
Download or read book Predicting the Total Charm Cross Section written by and published by . This book was released on 2008 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: We discuss the energy dependence of the total charm cross section and some of its theoretical uncertainties including the quark mass, scale choice and the parton densities. Extracting the total charm cross section from data is a non-trivial task. To go from a finite number of measured D mesons in a particular decay channel to the total c{bar c} cross section one must: divide by the branching ratio for that channel; correct for the luminosity, [sigma]{sub D} = N{sub D}/Lt; extrapolate to full phase space from the finite detector acceptance; divide by two to get the pair cross section from the single Ds; and multiply by a correction factor to account for unmeasured charm hadrons. Early fixed-target data were at rather low p{sub T}, making the charm quark mass the most relevant scale. At proton and ion colliders, although the RHIC experiments can access the full pT range and thus the total cross section, the data reach rather high p{sub T}, p{sub T}” m, making p{sub T} (m{sub T}) the most relevant scale. Here we focus on the total cross section calculation where the quark mass is the only relevant scale.
