Book Measurement of the Hadronic Cross Section in Electron positron Annihilation

Download or read book Measurement of the Hadronic Cross Section in Electron positron Annihilation written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the most precise measurement to date of the ratio R, the hadronic cross section in lowest order electron-positron annihilation to the cross section for muon pair production in lowest order electron-positron annihilation. This experiment is of interest because R is a fundamental parameter that tests in a model independent way the basic assumptions of strong interaction theories. According to the assumptions of one of these theories the value of R is determined simply from the electric charges, spin, and color assignments of the produced quark-pairs. The experiment was carried out with the MAgnetic Calorimeter using collisions of 14.5 GeV electrons and positrons at the 2200m circumference PEP storage ring at SLAC. The MAC detector is one of the best-suited collider detectors for measuring R due to its nearly complete coverage of the full angular range. The data for this experiment were accumulated between February 1982 and April 1983 corresponding to a total event sample of about 40,000 hadronic events. About 5% of the data were taken with 14 GeV beams and the rest of the data were taken with 14.5 GeV beams. A description of particle interactions and experimental considerations is given.

Book The Anomalous Magnetic Moment of the Muon

Download or read book The Anomalous Magnetic Moment of the Muon written by Fred Jegerlehner and published by Springer Science & Business Media. This book was released on 2008 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the present state of knowledge of the anomalous magnetic moment a=(g-2)/2 of the muon. The muon anomalous magnetic moment is one of the most precisely measured quantities in elementary particle physics and provides one of the most stringent tests of relativistic quantum field theory as a fundamental theoretical framework. It allows for an extremely precise check of the standard model of elementary particles and of its limitations.

Book Precise Measurement of the Total Cross Section

Download or read book Precise Measurement of the Total Cross Section written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This note will analyze the problems involved in making a precise measurement of the total cross secton for ee− annihilation into hadrons. Based on this analysis, we will suggest that a relatively simple non-magnetic device employing calorimetry over a 4.pi. solid angle is the optimum apparatus for such a measurement. We will describe one such device in some detail.

Book Total and Inclusive Hadron Production by Ee Annihilation At Sqrt S

Download or read book Total and Inclusive Hadron Production by Ee Annihilation At Sqrt S written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements are presented of R, the ratio of the total hadronic cross section to the cross section for mu pair production, and of the inclusive charged particle momentum distribution so sigma/dx for e/sup +/e− annihilation at center of mass energies of 5.2, 6.5, and 29.0 GeV. The ratio R is found to be approximately 3.9, consistent with quark-parton model expectations, at each of the three energies with an estimated systematic uncertainty of 6%. The inclusive cross sections show significant deviation from the scaling behavior predicted by the quark-parton model.
