CMS detector performance plots of heavy flavor decays using early Run 3 data

The document presents a series of performance plots for heavy flavor decays using an early Run 3 data sample collected by the CMS experiment in 2023. It highlights the impact of the new trigger strategy and detector upgrades on various observables. We showcase the dimuon mass distributions spanning a mass range of $[0.2, 11.5]$ GeV. Subsequently, we display the mass distributions for several B hadron states and the $\mathrm{X(3872)}$, using an integrated luminosity of $10 \; \text{fb}^{-1}$. For the $\mathrm{B^+} \to \mathrm{J/\psi K^+}$ decay, we also present the proper decay length distribution.
