Study of B \(\rightarrow\) \(D_{s}^{(*)+}X\) and \(B^{0}\) \(\rightarrow\) \(D_{s}^{(*)+}D^{*-}\) decays with the BABAR detector
- Precise measurements of \(D_{s}^{+}\) and \(D_{s}^{*+}\) meson production from B mesons and qqbar continuum events near the Upsilon(4S) resonance are presented in this document. Using the BABAR data recorded in 1999 and 2000 of 20.8 fb-1 on-resonance and 2.6 fb-1 off-resonance, the inclusive branching fractions of \(D_{s}^{(*)+}\) mesons from B decays have been measured. The branching fractions (BR(B \(\rightarrow\) \(D_{s}^{(*)}\) + \(D^{(*)})\)) and (BR(B \(\rightarrow\) \(D_{s}^{*}\) + \(D^{(*)}\))) have been determined from the fit of the measured \(D_{s}^{(*)+}\) momentum spectra. The study of different fragmentation functions and production cross sections measurement were done for the \(D_{s}^{(*)+}\) momentum spectrum produced from qqbar continuum events. Employing a partial reconstruction technique, the branching fractions of the \(B^{0}\)\(\rightarrow\)\(D_{s}^{(*)}\)+\(D^{*-}\) decays have been determined. From the angular analysis of \(B^{0}\)\(\rightarrow\)\(D_{s}^{*}\)+\(D^{*-}\) mode the fraction of longitudinal polarization is determined.
