Download or read book Diphoton and Photon + B/c Cross Sections at CDF II. written by A. Bocci and published by . This book was released on 2004 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: A measurement of the rate of prompt diphoton production in p{bar p} collisions at {radical}s = 1.96 TeV using the CDF detector is presented. The results are compared to a NLO calculation. they also measured the {gamma} + b and {gamma} + c cross sections comparing the results with PYTHIA LO predictions. The background from non-prompt sources is estimated using a statistical method based on differences in electromagnetic showers initiated by photons and by the background.
