Determination of $P(c \to D^{*+})$ and $BR(c \to l^{+})$ at LEP 1 / DELPHI Collaboration
The probability $P(c \rightarrow D^{*+})$ that a charm quark fragments into a $D^{*+}$ meson and the $c \rightarrow l^+$ semileptonic branching fraction were measured in $Z^0\ $ decay into $c\bar{c}$ events. \par % A double tag method based % on the detection of exclusively reconstructed $D$ mesons % accompanied by a slow pion or a lepton in the opposite hemisphere was used.\par From the analysis of 3.5 Million $Z^0\ $ events collected from 1992 to 1995, a sample of charm meson decays with $81\%$ $c\bar{c}$ purity was selected [...]
