Abstract
We measure the per-event production rate and momentum spectrum of D0 mesons created in electron-positron annihilations via the process e+e_ annihilation goes to quark-antiquark hadrons at 10.54 GeV center-of-mass energy. The data was collected over a period of stable running by the BABAR Experiment at the Stanford Linear Accelerator Center (now SLAC National Accelerator Laboratory). In this study, we reconstruct the D0 meson through its decay D0 ->K- π+π0. Using the known branching ratio for this mode, and efficiencies estimated from Monte Carlo simulation studies, we find that on average 0.092 D0 mesons are produced per e+eannihilation. This information improves the current knowledge of hadron production from electron-positron annihilation and helps gain a better understanding of Quantum Chromodynamics and hadronic matter production.
