Description
The LHCb experiment operates at the Large Hadron Collider in an environment characterized by extreme collision rates and abundant QCD backgrounds. With a primary focus on heavy flavour physics, often involving subtle signatures, the experiment is designed to maximize its physics reach by reading out the detector at every bunch crossing. This results in a raw data rate of approximately 4 TB/s, far exceeding what can be stored. This talk describes how LHCb meets the resulting challenge through a fully software-based real-time reconstruction and selection pipeline, and how this architecture directly shapes the experiment's physics reach.
