Measurement of the near-threshold $e^{+}{e}^{-}\to D\bar{D}$ cross section using initial-state radiation

Abstract

We report measurements of the exclusive cross section for $e^{+}{e}^{-}\to D\bar{D}$, where $D=D^0$ or $D^{+}$, in the center-of-mass energy range from the $D\bar{D}$ threshold to $5\mathrm{GeV}/c^2$ with initial-state radiation. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 673 ${\mathrm{fb}}^{-1}$.

Presented at EPS07 and LP07 conferences, published in PRD(RC)
