A Lightweight First-Level Muon Track Trigger for Future Hadron Collider Experiments

Single muon triggers are crucial for the physics programmes at hadron collider experiments. To
keep the trigger rates reasonably low they must be highly selective.
Muon systems at LHC experiments and at future colliders use two muon chamber system for
triggering: fast trigger chambers to identify the bunch crossing and provide a coarse momentum
estimation, and slower precision chambers, for precise measurements of the muon trajectory.
A fast lightweight track finding algorithm, based on the Hough Transform and Linear Regression
techniques, has been designed and implemented on a Zynq SoC device, reconstructing successfully muon tracks in a single trigger sector.
