Search for the decay B_s⁰ → D^*+D^*− with the LHCb experiment — Sophie Hollit, 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. Besides the primary aim of observing the decay B_s⁰ → D^*+D^*−, this analysis also aims to measure the branching ratio relative to the decay B⁰ → D^*+D^*−. By measuring the relative branching ratio, dominant systematic uncertainties can be cancelled.

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