DESCRIPTION:Speakers: Arantza Oyanguren\n\nThe new fully software-based tr
 igger of the LHCb experiment at CERNoperates at a 30 MHz data rate\, openi
 ng a search window into previouslyunexplored regions of the physics phase 
 space. The BuSca (BufferScanner) project at LHCb acquires and analyses dat
 a in real time\, priorto any trigger decision\, extending sensitivity to n
 ew lifetimes and massranges thanks to the recently deployed Downstream alg
 orithm\,specifically designed to reconstruct displaced tracks that origina
 tedownstream of the vertex detector. BuSca identifies hotspots in the data
 indicative of potential new long-lived particle candidates in amodel-indep
 endent manner\, providing strategic guidance for developingnew trigger lin
 es. To control background\, regions with minimal detectormaterial interact
 ions are selected\, and pairs of same-sign tracks areused to suppress comb
 inatorial background. In this talk\, I will presentthe current status and 
 future prospects of this pioneering framework\,along with the results from
  the analysis of the first data.\n \nhttps://stanford.zoom.us/j/989731562
