Abstract

The latest and improved measurements in B⁰_(s)→μ⁺ μ^- processes have been performed by LHCb using full Run 1 and Run 2 data. The measurement of the branching fraction of B⁰_s→μ⁺ μ^- is presented as the most precise single experiment measurement of such a rare process. While no significant excess is found for B⁰→μ⁺ μ^-, an stringent upper limit is set for its braching fraction. Both results are in agreement with SM predictions and with previous results.
