Description
For Run 3 of the LHC, the LHCb experiment has introduced, among others, two novel reconstruction methods. One targets long-lived particles. It uses the new fully software-based trigger operating at a 30 MHz data rate, opening a search window into previously unexplored regions of physics phase space. The BuSca (Buffer Scanner) method acquires and analyzes data in real time, extending sensitivity to new lifetimes and mass ranges thanks to the recently deployed Downstream tracking algorithm. The other new method aims at the direct reconstruction of charged heavy-flavour particles using hits in the VELO sub-detector, located closest to the beamline. This technique is designed to enhance signal purity in challenging analyses that involve missing energy and vertex information, particularly those with neutrinos and tau leptons in the final state. For both methods, the design, implementation and some selected performance studies on both real and simulated Run 3 data will be shown, including highlighting its impact on key physics analyses.
