Semi-automated BSM model building procedures in MARTY-1.1 through a 2HDM example
/ Uhlrich, G. ; Mahmoudi, F. ; Arbey, A.
MARTY is a C++ computer algebra system specialized for High Energy Physics that can calculate amplitudes, squared amplitudes and Wilson coefficients in a large variety of beyond the Standard Model scenarios up to the one-loop order. It is fully independent of any other framework and its main development guideline is generality, in order to be adapted easily to any type of model. [...]

Let’s get our hands dirty: a comprehensive evaluation of DAQDB, key-value store for petascale hot storage
/ Abed Abud, Adam (CERN) ; Cicalese, Danilo (CERN) ; Jereczek, Grzegorz (IMP, Gdansk) ; Goff, Fabrice Le (CERN) ; Lehmann Miotto, Giovanna (CERN) ; Love, Jeremy (Argonne (main)) ; Maciejewski, Maciej (IMP, Gdansk) ; Mommsen, Remigius K (Fermilab) ; Radtke, Jakub (IMP, Gdansk) ; Schmiegel, Jakub (IMP, Gdansk) et al.
Data acquisition systems are a key component for successful data taking in any experiment. The DAQ is a complex distributed computing system and coordinates all operations, from the data selection stage of interesting events to storage elements. [...]

The Acts project: track reconstruction software for HL-LHC and beyond
/ Gessinger, Paul (CERN ; Mainz U.) ; Grasland, Hadrien (CENBG, Gradignan) ; Gray, Heather (LBL, Berkeley ; UC, Berkeley) ; Kiehn, Moritz (U. Geneva (main)) ; Klimpel, Fabian (CERN ; Tech. U., Munich (main)) ; Langenberg, Robert (CERN) ; Salzburger, Andreas (CERN) ; Schlag, Bastian (CERN ; Mainz U.) ; Zhang, Jin (ICTS, Beijing) ; Ai, Xiaocong (UC, Berkeley)
The reconstruction of trajectories of the charged particles in the tracking detectors of high energy physics (HEP) experiments is one of the most difficult and complex tasks of event reconstruction at particle colliders. As pattern recognition algorithms exhibit combinatorial scaling to high track multiplicities, they become the largest contributor to the CPU consumption within event reconstruction, particularly at current and future hadron colliders such as the LHC, HL-LHC and FCC-hh.

Towards a Turnkey Software Stack for HEP Experiments
/ Sailer, André (CERN) ; Ganis, Gerardo (CERN) ; Mato, Pere (CERN) ; Petrič, Marko (CERN) ; Stewart, Graeme A (CERN)
Future HEP experiments require detailed simulation and advanced reconstruction algorithms to explore the physics reach of their proposed machines and to design, optimise, and study the detector geometry and performance. To synergize the development of the CLIC and FCC software efforts, the CERN EP R&D; roadmap proposes the creation of a “Turnkey Software Stack”, which is foreseen to provide all the necessary ingredients, from simulation to analysis, for future experiments; not only CLIC and FCC, but also for proposed Super-tau-charm factories, CEPC, and ILC.

Reconstruction of track candidates at the LHC crossing rate using FPGAs
/ Tuci, Giulia (INFN, Pisa ; Pisa U.) ; Punzi, Giovanni (INFN, Pisa ; Pisa U.)
/LHCb RTA project Collaboration
In 2021 the LHCb experiment will be upgraded, and the DAQ system will be based on full reconstruction of events, at the full LHC crossing rate. This requires an entirely new system, capable of reading out, building and reconstructing events at an average rate of 30 MHz. [...]

Searching for lepton number violating $\Lambda$ baryon decays mediated by GeV-scale Majorana neutrino with LHCb
/ Zhang, Guangshuai (Peking U. ; Peking U., SKLNPT) ; Ma, Bo-Qiang (Peking U. ; Peking U., SKLNPT ; Peking U., CHEP ; CICQM, Beijing)
We consider the lepton-number-violating processes in $\Lambda_b$/$\Lambda_c$ decays mediated by on-shell GeV-scale sterile neutrino. We calculate the branching ratio for the following processes: $\Lambda_b^{0} \rightarrow \mathcal{B}^+ \mu^{-}\mu^- \pi^+$, where $\mathcal{B}^+$ is $\Lambda_c^+$ or proton, and $\Lambda_c^{+} \rightarrow \Lambda \mu^{+}\mu^+ \pi^-$, as function of the mass of the sterile neutrino $m_N$ and the heavy-light mixing coefficient of the extended Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix $|U_{\mu N}|^2$.
