Search for the decay B_s⁰ → D^*+D^*− with the LHCb experiment — Philipp Ibis, •Jan Langer, and Antje Mödden — Experimentelle Physik 5, TU Dortmund

At the LHCb experiment precise measurements are performed to search for physics beyond the Standard Model. For this it is important to observe new decays and measure their branching ratio. The aim of this analysis is to observe the decay B_s⁰ → D^*+D^*− and to measure the branching ratio relative to the decay B_d⁰ → D^*+D^*−. This cancels dominant, systematic uncertainties in the relative branching ratio. This analysis can also be used to perform an angular analysis and a time-dependent measurement of CP violation in the control channel.

The current status of the analysis, in which the full data set of the LHCb experiment corresponding to an integrated luminosity of 9 fb⁻¹, is presented.
