Flavour Changing Neutral Current processes are heavily suppressed in the Standard Model of particle physics and are potentially sensitive to contributions from as yet undiscovered particles. Recent measurements of b→s transitions by the LHCb collaboration show interesting tensions with Standard Model predictions.
The large LHC data set enables measurements of decays involving b→d transitions to be made for the first time. In combination with the b→s processes, these measurements will provide insights into the flavour structure of potential extensions to the Standard Model. The decay B0→ρ0μ+μ- is a particularly interesting b→d process, which was first probed using LHCb's Run 1 dataset. Progress towards an updated branching fraction measurement, using both Run 1 and Run 2 data, will be presented. In addition, the prospects for an angular analysis of the decay are discussed.
