Development of flavour-tagging algorithms for the LHCb in Run 3 — •Jonas Rönsch, Johannes Albrecht, Quentin Führing, and Vukan Jectić — TU Dortmund University, Dortmund, Germany

The Standard Model allows the oscillation of the flavour from neutral B mesons, which can lead to a change in flavour between production and decay. For studies in the field of heavy flavour physics, e.g. analyses of CP violation in the decay of neutral B mesons, knowledge of the initial flavour is necessary. This information can be retrieved through the process of flavour-tagging. At the LHCb experiment, a flavour-tagging technique involving the charge of particles which are connected to the production flavour of the B meson. For Run 3 of the LHC, most components of the LHCb detector were upgraded. Consequently, the existing flavour-tagging algorithms must be revisited and adapted according to the Run 3 detector conditions. The reimplementation and optimization of the flavour tagging algorithms based on simulated Run 3 data samples will be presented in this contribution.
