 Bayesian inference for form-factor fits regulated by unitarity and analyticity / Flynn, J.M. ; Jüttner, A. ; Tsang, J.T. We propose a model-independent framework for fitting hadronic form-factor data, which is often only available at discrete kinematical points, using parametristations based on to unitarity and analyticity.

 Exclusive semileptonic $B_s\to K \ell \nu$ decays on the lattice / Flynn, J.M. (Southampton U.) ; Hill, R.C. (Edinburgh U.) ; Jüttner, A. (Southampton U. ; CERN) ; Soni, A. (Brookhaven) ; Tsang, J.T. (CERN) ; Witzel, O. (U. Siegen (main)) Semileptonic $B_s \to K \ell \nu$ decays provide an alternative $b$-decay channel to determine the CKM matrix element $|V_{ub}|$, and to obtain a $R$-ratio to investigate lepton-flavor-universality violations.

 Development of a DAQ system for the CMS ECAL Phase 2 recommissioning / Chiusi, Marco (Ecole Polytechnique) /CMS Collaboration In view of the High-Luminosity phase of the Large Hadron Collider (LHC), in the barrel region of the CMS electromagnetic calorimeter (ECAL) the entire readout electronics will be replaced to cope with the more stringent requirements in terms of trigger latency, acquisition rate, and radiation and pileup resilience. The configuration sequence for the new on-detector electronics, involving both the improved very-front-end and front-end cards, is reported. The sequence of commands and parameters to load in the electronics is controlled by a software developed at CERN by the ECAL upgrade group and it will be the base on which to build the new data acquisition system (DAQ)..

 CMS tracking performance in Run 2 and early Run 3 data using the tag-and-probe technique / D'anzi, Brunella (INFN, Bari ; Bari U.) /CMS Collaboration Accurate reconstruction of charged particle trajectories and measurement of their parameters (tracking) is one of the major challenges of the CMS experiment. A precise and efficient tracking is one of the critical components of the CMS physics program as it impacts the ability to reconstruct the physics objects needed to understand proton-proton collisions at the LHC.

 The Level 1 Scouting system of the CMS experiment / James, Thomas Owen (CERN) /CMS Collaboration A novel data collection system, known as Level-1 (L1) Scouting, is being introduced as part of the L1 trigger of the CMS experiment at the CERN Large Hadron Collider. The L1 trigger of CMS, implemented in FPGA-based hardware, selects events at 100 kHz for full read-out, within a short 3~microsecond latency window. [...] CMS-CR-2023-024.- Geneva : CERN, 2023 - 8 p.
