Search for the rare decay D${}^0$ $\to$ ${\mu }^{+}{\mu }^{-}$ in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV

CMS Collaboration

A search for the rare decay D${}^0$ $\to$ ${\mu }^{+}{\mu }^{-}$ is reported using proton-proton collision events at $\sqrt{s}$ = 13.6 TeV collected by the CMS detector in 2022$-$2023, correspondi…
