Charm meson spectra in e^+e^- annihilation at 10.5 GeV center of mass energy

Creators

Abstract

Using the CLEO detector at the Cornell Electron-positron Storage Ring, we have measured the scaled momentum spectra, dσ/dx_p, and the inclusive production cross sections of the charm mesons D^+, D^0, D^(⋆+), and D^(⋆0) in e^+e^− annihilation at about 10.5 GeV center of mass energy, excluding the decay products of B mesons. The statistical accuracy and momentum resolution are superior to previous measurements at this energy.
