Search for rare muonic B decays at CMS / Szlezak, Klara Emilia (Warsaw U.) /CMS Collaboration
In this paper, we present the search for three highly suppressed Standard Model processes at the CMS experiment: B0→μ+μ−, Bs0→μ+μ−, and Bs0→μ+μ−γ. The latest and most precise results to date are presented for the first two decays, while the feasibility and experimental strategy for the third, yet unobserved at CMS, are discussed. [...]

Recent Experience with the CMS Data Management System / Ozturk, Hasan (CERN) ; Paparrigopoulos, Panos (CERN) ; Manrique Ardila, Andres (Wisconsin U., Madison) ; Chauhan, Rahul (Wisconsin U., Madison) ; Ellis, Katy (Rutherford) ; Emmanouil, Christos (CERN) ; Kovalskyi, Dmytro (MIT) ; Vaandering, Eric Wayne (Fermilab) ; Voetberg, Margaret Grace (Fermilab) ; Wightman, Andrew Steven (Nebraska U.) /CMS Collaboration
The CMS experiment manages a large-scale data infrastructure, currently handling over 200 PB of disk and 500 PB of tape storage and transferring more than 1 PB of data per day on average between various WLCG sites. Utilizing Rucio for high-level data management, FTS for data transfers, and a variety of storage and network technologies at the sites, CMS confronts inevitable challenges due to the system's growing scale and evolving nature.

Projections for Key Measurements in Heavy Flavour Physics / ATLAS, The ; II, Belle ; Cms /ATLAS Collaboration ; Belle II Collaboration ; CMS Collaboration ; LHCb Collaboration
Precision studies of flavour-changing processes involving quarks and leptons provide a number of ways to improve knowledge of the Standard Model and search for physics beyond it. There are excellent short- and mid-term prospects for significantly improved measurements in heavy flavour physics (involving b and c hadrons and τ leptons), with upgrades in progress or planned for the ATLAS, CMS and LHCb experiments exploiting proton-proton collisions at CERN's Large Hadron Collider, and for the Belle II experiment operating with electron-positron collisions from the SuperKEKB accelerator in KEK.
