Measurement of the branching ratio of Bs0D D with the LHCb experimentPhilipp Ibis, •Antje Mödden, and Margarete Schellenberg — Experimentelle Physik 5, TU Dortmund

Precision measurements testing the Standard Model are performed at the LHCb experiment, two important goals of which are the observation of new decays and measurements of their branching ratios. Although the decay Bs0D D has not yet been experimentally observed, an excess of Bs0D D candidates has been seen in the measurement of CP violation in the B0D D decay. By measuring the branching ratio relative to the decay B0D D, most uncertainties cancel due to the similarity of both decay channels.
The talk will cover the current status of the analysis of the branching ratio of the decay Bs0D D using the full dataset of the LHCb experiment corresponding to an integrated luminosity of 9 fb−1.
