Analysis of Bs,d0→µ+µ− decays with the full LHCb dataset — Johannes Albrecht, •Maik Becker, and Titus Mombächer — Experimentelle Physik 5, TU Dortmund
The first observation of the decay Bs0→µ+µ− with a single experiment was reported by the LHCb collaboration in 2017 with a significance of 7.8σ using data corresponding to 4.4 fb−1 of integrated luminosity. The measurement demonstrated the excellent sensitivity of the LHCb experiment in this channel, but no deviations from the Standard Model predictions were found, introducing strong constraints to New Physics models. Since the uncertainty on the result is driven by statistical limitations, an analysis with a larger dataset and improved methods is performed, which may also allow for the first observation of the decay Bd0→µ+µ−.
In this talk the ongoing measurement of Bs,d0→µ+µ− with the full LHCb dataset corresponding to 9 fb−1 will be presented.
