Evidence for CP violation and measurement of CP-violating parameters in B0sJ/ψϕ(1020)B0sJ/ψϕ(1020) decays in pp collisions at s=s= 13 TeV / CMS Collaboration
A pioneering machine-learning-based flavor-tagging algorithm combining same-side and opposite-side tagging is used to obtain the equivalent of 27 500 tagged B0sJ/ψϕ(1020)B0sJ/ψϕ(1020) decays from pp collisions at s=s= 13 TeV, collected by the CMS experiment and corresponding to an integrated luminosity of 96.5 fb11.

An integrated flux-symmetric spectrometer-magnet system for the SND@LHC experiment upgrade / SND@LHC Collaboration
The proposed upgrade of the SND@LHC experiment for the High Luminosity phase of the LHC (HL-LHC) will strongly benefit from the presence of a magnetized region, allowing for muon momentum and chargemeasurement. In this paper we describe an iron core magnet system that is partly integrated with the calorimeter and that is designed to respect the strict constraints from the available space in the experimental cavern, power consumption, and field requirements.Semi-analytical tools are introduced to explore the parameter space, in order to define the primary design options. [...]
