Inclusive B-meson flavour-tagging algorithm at LHCb. J. High Energ. Phys. 2025, 41 (2025). https://doi.org/10.1007/JHEP11(2025)0411029-8479https://hdl.handle.net/2183/49135[Abstract] A new algorithm is developed to identify the flavour of neutral B mesons at production in pp collisions by utilising all tracks from the hadronisation process. The algorithm is calibrated separately for B0 and mesons using B0 → J/ψK+π− and decays from pp collision data collected by the LHCb experiment at a centre-of-mass energy of 13 TeV. This new algorithm improves the tagging power by 35% for B0 mesons and 20% for mesons when compared to the combined performance of the existing LHCb flavour-tagging algorithms.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/B PhysicsCP ViolationFlavour PhysicsHadron-Hadron Scatteringjournal articleopen access10.1007/JHEP11(2025)041
