N2 - A search for the very rare B∗0→μ+μ- and Bs∗0→μ+μ- decays is conducted by analysing the Bc+→π+μ+μ- process. The analysis uses proton-proton collision data collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9\,fb-1. The signal signatures correspond to simultaneous peaks in the μ+μ- and π+μ+μ- invariant masses. No evidence for an excess of events over background is observed for either signal decay mode. Upper limits at the 90% confidence level are set on the branching fractions relative to that for Bc+→J/ψπ+ decays, (Formula presented.)
