Description
Allen is the GPU implementation of the High Level Trigger of LHCb. It is able to run the full reconstruction at a 30 MHz and reduce the rate by a factor of 30/60.
A tracking algorithm using only the VErtex LOcator (VELO) and the MUON system, implemented in the Allen framework, is presented. The long distance between the VELO and the MUON systems - together with a precise parametric description of the LHCb magnetic field makes possible a 4-5% momentum resolution despite a spatial resolution of O(10cm) per hit in the MUON segment. These tracks are then used to produce dimuon candidates using the precise resolution of the VELO.
