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 this year, 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-pT objects in the event. [...]

Tracking on GPU at LHCb’s fully software trigger
/ Scarabotto, Alessandro (Centre National de la Recherche Scientifique (FR))
The LHCb experiment will use a fully software-based trigger to collect data from 2022 on, at an event rate of 30 MHz. During the first stage of the High-Level Trigger (HLT1), a partial track reconstruction, using efficient parallelisation techniques on GPU cards, is performed. [...]

Quarkonia production in (ultra-)peripheral PbPb collisions at LHCb
/ Wang, Xiaolin (South China Normal University (CN))
The cross-sections of coherent $J/\psi$ and $\psi (2S)$ production in ultra-peripheral PbPb collisions at a nucleon-nucleon centre-of-mass energy of $5.02\,\mathrm{TeV}$ are measured using a data sample collected in 2018 at LHCb, and the differential cross-sections are measured separately as a function of transverse momentum and rapidity. The photo-production of $J/\psi$ mesons at low transverse momentum is studied in peripheral PbPb collisions, $J/\psi$ candidates are reconstructed through the prompt decay into $\mu^+\mu^-$ in the rapidity region of $2.0 < y < 4.5$ [...]

New software technologies in the LHCb Simulation
/ Mazurek, Michal (National Centre for Nuclear Research (PL)) ; Corti, Gloria (CERN) ; Kreps, Michal (University of Warwick (GB)) ; Davis, Adam (University of Manchester (GB)) ; Popov, Dmitry (University of Chinese Academy of Sciences (CN)) ; Siddi, Benedetto Gianluca (Universita e INFN, Ferrara (IT))
Monte Carlo simulations are key to the design and commissioning of new detectors as well as the interpretation of physics measurements. The amount of simulated samples required for the Run 3 physics program of the LHCb experiment will increase significantly from 2022 onward to match the increase in the amount of data collected with respect to Run 1 and 2 operation. [...]
