Angular analysis of the e+e−→D(*)±D*∓ process near the open charm threshold using initial-state radiation
Angular analysis of the e+e−→D(*)±D*∓ process near the open charm threshold using initial-state radiation
We report a new measurement of the exclusive ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{(*)\ifmmode\pm\else\textpm\fi{}}{D}^{*\ensuremath{\mp}}$ cross sections as a function of the center-of-mass energy from the ${D}^{(*)\ifmmode\pm\else\textpm\fi{}}{D}^{*\ensuremath{\mp}}$ threshold through $\sqrt{s}=6.0\text{ }\text{ }\mathrm{GeV}$, using the initial-state radiation technique. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of $951\text{ …
