  1. Measurements of Charm Meson Production in 10.5 GeV Electron -Positron Annihilations

    Johnson, Edward EricUniversity of Illinois at Urbana-Champaign2015

    A study of charm meson production in e+ e- gamma* → cc¯ events at s = 10.5 GeV is presented. Included are measurements of the fragmentation distributions of D+s and D*+s , the vector to pseudoscalar production ratio for Ds, and the D*+ spin alignment. A description of the new trigger …

  3. Study of D-star mesons produced in electron positron annihilations at 4.14 GeV center of mass energy

    Simopoulos, Constantine2011

    Charmed D* mesons produced in e+e-annihilations at a center of mass energy of 4.14 GeV are observed by the Mark III detector at SPEAR. The recoil mass spectrum of the D mesons is used to extract the branching fractions of the charged and neutral D*. Measurements are presented for the two decay …
