A first look into 2026 LHCb data

Titor: Camille Normand

Supervisor: Camille Normand

With the acquisition of new data at a faster pace than ever, maintaining and verifying its quality is of paramount importance for greater precision measurements and improved searches for physics beyond the Standard Model at LHCb. In this project, the student will give the very first look at the newly-acquired 2026 data, i.e. only a few months old, through the study of the decay B→KS J/ψ. This high-statistics channel allows for a very clear study of, on the one hand, reconstruction effects, providing results of great impact for the whole collaboration, and on the other hand, detailed aspects of signal selection tools such as ML algorithms and particle identification, directly contributing to a world-leading search for New Physics. In both aspects, the student will have the opportunity to develop their knowledge of standard Particle Physics techniques, as well as develop their own tools and measurables for data and simulation quality evaluations.
