Abstract
The analysis of the B0 → X(3872)K0 S production channel of the tetraquark candidate X(3872), performed on CMS data acquired during LHC Run 3, is here presented. We characterised the performance of the new low-pT dimuon trigger configuration implemented in Run 3 used for the analysis and estimated its impact on signal selection efficiency, which suggests a significant improvement with respect to Run 2 triggers. Finally, preliminary results on the control channel are presented, showing good agreement between data and Monte Carlo and resulting in a branching ratio measurement compatible with the world average. The present analysis has yet to be fully validated by the CMS Collaboration, therefore only preliminary results will be presented.
