Event and data persistency models for the LHCb Real Time Analysis System / Cian, Michel De (Heidelberg U.) ; Esen, Sevda (Heidelberg U.) ; Hennequin, Arthur (CERN) ; Vilasís-Cardona, Xavier (Ramon Llull U., Barcelona)
Starting in 2022, the upgraded LHCb detector is collecting data with a pure software trigger. In its first stage, reducing the rate from 30MHz to about 1MHz, GPUs are used to reconstruct and trigger on B and D meson topologies and high-pT objects in the event. [...]

Fast and flexible data structures for the LHCb Run 3 software trigger / Esen, Sevda (University of Zurich (CH)) ; Hennequin, Arthur Marius (Massachusetts Inst. of Technology (US)) ; De Cian, Michel (EPFL - Ecole Polytechnique Federale Lausanne (CH))
Starting in 2022, the upgraded LHCb detector will collect data with a pure software trigger. In its first stage, reducing the rate from 30MHz to about 1MHz, GPUs are used to reconstruct and trigger on B and D meson topologies and high-$p_T$ objects in the event. [...]

6. Particle identification performance of the LHCb experiment in Run 2
Reference: Poster-2019-697
Created: 2019. -1 p
Creator(s): Douglas, Lauren Marie; De Cian, Michel

The LHCb particle identification (PID) system is composed of two ring-imaging Cherenkov detectors, a series of muon chambers and a calorimeter system. A novel strategy has been introduced in Run 2, where the selection of PID calibration samples for charged particles and neutrals is implemented in the LHCb software trigger. A further processing of the data is required in order to provide samples for the determination of PID performance, which is achieved through a centralised production that makes highly efficient use of computing resources. This talk covers the major steps of the implementation, and highlights the PID performance achieved in Run 2.

Status of HLT1 sequence and path towards 30 MHz / De Cian, Michel (EPFL - Ecole Polytechnique Federale Lausanne (CH)) ; Dziurda, Agnieszka (CERN) ; Gligorov, Vladimir (Centre National de la Recherche Scientifique (FR)) ; Hasse, Christoph (Technische Universitaet Dortmund (DE)) ; Hulsbergen, Wouter (Nikhef National institute for subatomic physics (NL)) ; Latham, Thomas Edward (University of Warwick (GB)) ; Ponce, Sebastien (CERN) ; Quagliani, Renato (Université Paris-Saclay (FR)) ; Schreiner, Henry Fredrick (University of Cincinnati (US)) ; Stemmle, Simon Benedikt (Ruprecht Karls Universitaet Heidelberg (DE)) et al.
We present the current status of the HLT1 reconstruction sequence for the LHCb upgrade, both in terms of the number of events which can be processed per second and the achievable physics performance on a selected range of benchmark modes. We present detailed profiling of the various algorithms, describe the bottlenecks, and outline a strategy towards an HLT1 able to process the LHCb upgrade data at 30 MHz

Fast neural-net based fake track rejection in the LHCb reconstruction / De Cian, Michel (Ruprecht-Karls-Universitaet Heidelberg (DE)) ; Farry, Stephen (University of Liverpool (GB)) ; Seyfert, Paul (Universita & INFN, Milano-Bicocca (IT)) ; Stahl, Sascha (CERN)
A neural-network based algorithm to identify fake tracks in the LHCb pattern recognition is presented. This algorithm, called ghost probability, retains more than 99 % of well reconstructed tracks while reducing the number of fake tracks by 60 %. [...]
