The study of charge asymmetries in three-body 𝐵 ± → h h h decays provides a sensitive probe of CP violation in the beauty sector. Using the first data collected during LHCb Run 3, we are performing a preliminary investigation aimed at measuring these asymmetries through fits to the invariant mass distributions of selected candidates. The upgraded detector and higher instantaneous luminosity of Run 3 are expected to improve signal-to-background separation and reduce systematic uncertainties, offering enhanced sensitivity compared to previous runs. This ongoing study will lay the groundwork for precise tests of the Standard Model and potential exploration of effects beyond it.
