Descripción

The LHCb Upgrade in Run 3 has changed its trigger scheme for a full software selection in two steps. The first step, HLT1, is entirely implemented on GPUs and is running on real time a fast selection to reduce the collision rate from 30 MHz to 1 MHz.

In this talk we will discuss the design and implementation of several algorithms which are focused on the reconstructions of tracks downstream the magnet, using the new Scintillating-Fiber tracker (Scifi) and the silicon strip Upstream Tracker (UT) detectors. Those algorithms are crucial for detecting long-lived particles of SM and BSM.
