The CMS Drift Tube (DT) trigger system reconstructs muon signals with great efficiency by correlating signals inside each DT chamber. A new layer of FPGA-based electronics, the so-called DT Phase 2 Filter, capable of simultaneously correlate information from several DTs, will be included in the CMS Muon system for the upcoming era of the High Luminosity LHC. A review of the different...
As we push to increase the instantaneous luminosity of the ATLAS detector, strict requirements on events are needed in order to reduce the output rate to the desired 1-1.5kHz. We can be clever about how we select events; imposing topological requirements through kinematic and angular cuts on combinations of particles allows us to further reduce the event rate without having to tighten the...
Abstract:
Neutral pions and photons play a crucial role in the LHCb physics program since they are used in a variety of physics analyses. These particles are not electrically charged and therefore cannot be detected by the tracking system. Instead, their energy and position can only be measured by the electromagnetic calorimeter sub-detector (ECAL).
During Run I and Run II, energy and...
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...
Reconstruction algorithms or more generally any algorithm bound to serve in the trigger needs to fulfil given efficiencies and accuracies to comply with the physics necessities, but also be compatible with a given time budget. Increasing data throughputs are often a challenge that classical algorithms and approaches cannot sustain. For this reason, new strategies are required. Some techniques...
