CMS and LHCb have performed a search for the rare decays B⁰_s -> µ⁺µ^- and B⁰ -> µ⁺µ^- based on their full 2011 and 2012 data, each finding an excess of B⁰_s -> µ⁺µ^- events with > 4 sigma significance, and measuring branching fractions compatible with the Standard Model expectations.

Both experiments will present their results and discuss in particular the applied analysis techniques to cope with the experimental challenges.
