The LHCb detector at the Large Hadron Collider is designed for Physics beyond the Standard Model searches in charge-parity violation and rare decays. Decays of beauty mesons to open charm
final states also enable a wide spectrum of spectroscopy studies, especially investigation of $b\bar{b}$ and $b\bar{s}$ systems. New results, including Run 1 and Run 2 data set, with several new branching fraction measurements, are presented in this paper.
