Search for the Rare Decay ${D}^{0}→{μ}^{+}{μ}^{−}$ in Proton-Proton Collisions at $\sqrt{s}=13.6\text{ }\text{ }\mathrm{TeV}$
Author(s): V. Chekhovsky et al. (CMS Collaboration)
A search for the rare decay ${D}^{0}→{μ}^{+}{μ}^{−}$ is reported using proton-proton collision events at $\sqrt{s}=13.6\text{ }\text{ }\mathrm{TeV}$ collected by the CMS detector in 2022–2023, corresponding to an integrated luminosity of $64.5\text{ }\text{ }{\mathrm{fb}}^{−1}$. This is the first an… [Phys. Rev. Lett. 135, 151803] Published Thu Oct 09, 2025
