Abstract
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 evi- dence for an excess of events over background is observed for either signal decay mode. Upper limits at the 90% confi- dence level are set on the branching fractions relative to that for Bc+ → J/ψπ+ decays,

RB∗0+μ+/J/ψπ+ < 3.8 × 10−5 and
RBs∗0+μ+/J/ψπ+ < 5.0 × 10−5.
