Description
The new fully software-based trigger of the LHCb experiment at CERN operates at a 30 MHz data rate, opening a search window into previously unexplored regions of the physics phase space. The BuSca (Buffer Scanner) project at LHCb acquires and analyses data in real time, prior to any trigger decision, extending sensitivity to new particle lifetimes and mass ranges.
Displaced tracks that originate downstream of the LHCb vertex detector are reconstructed and selected. BuSca identifies hotspots in the data indicative of potential new long-lived particle candidates in a model-independent manner, providing strategic guidance for developing new trigger lines. In this talk, we will present the current status and potential developments of this pioneering framework, along with the results from the analysis of the Run 3 data.
