Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade.

Neustart des LHCb-Experiments Mit B-Mesonen auf der Suche nach neuer Physik alex seuthe | JOhannes albreCht Untersuchungen von B-Meson-Zerfällen in der Hochenergieteilchenphysik bilden zurzeit einen Fokus der Forschung am LHCb-Experiment. Der nach einer maßgeblichen Überarbeitung kürzlich wieder gestartete Teilchendetektor soll neues Licht auf diese Prozesse werfen. www.phiuz.de 3/2023 (54) Phys. Unserer Zeit 135
