Abstract
This work presents measurements of the raw asymmetry in the decays Λb → Λμμ via the ψ(2S) resonance, using data collected by the LHCb experiment during Run 2 (2016–2018). The analysis is performed separately for different track types (LL, DD) and magnet polarities (MU, MD) as well as for the merged datasets, with special attention to background suppression and signal modelling. After applying selection criteria and fitting the invariant mass distributions, the raw asymmetry is extracted. The results show no sign of significant CP violation within the experimental uncertainties.
