arXiv preprint arXiv:2409.17209, 2024•arxiv.orgA search for the very rare $ B^{* 0}\to\mu^+\mu^-$ and $ B_ {s}^{* 0}\to\mu^+\mu^-$ decays
is conducted by analysing the $ B_c^+\to\pi^+\mu^+\mu^-$ process. The analysis uses
proton-proton collision data collected with the LHCb detector between 2011 and 2018,
corresponding to an integrated luminosity of 9$\text {\, fb}^{-1} $. The signal signatures
correspond to simultaneous peaks in the $\mu^+\mu^-$ and $\pi^+\mu^+\mu^-$ invariant
masses. No evidence for an excess of events over background is observed for either signal …

A search for the very rare and decays is conducted by analysing the process. The analysis uses proton-proton collision data collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9$\text{\,fb}^{-1}$. The signal signatures correspond to simultaneous peaks in the and invariant masses. No evidence for an excess of events over background is observed for either signal decay mode. Upper limits at the confidence level are set on the branching fractions relative to that for $B_c^+\to J\mskip -3mu/\mskip -2mu\psi\pi^+$ decays, \begin{align*} {\cal R}_{B^{*0}(\mu^+\mu^-)\pi^+/J\mskip -3mu/\mskip -2mu\psi\pi^+} &< 3.8\times 10^{-5}\ \text{ and } {\cal R}_{B_{s}^{*0}(\mu^+\mu^-)\pi^+/J\mskip -3mu/\mskip -2mu\psi\pi^+} &< 5.0\times 10^{-5}\,. \end{align*}
