Observation of the different behaviour of baryonic matter and antimatter.
First observation of CP violation in baryon decays – an important milestone in the history of particle physics. Yesterday, at the Rencontres de Moriond EW, the LHCb collaboration reported the first observation of CP violation in baryon decays. The corresponding publication, submitted to Nature, appeared on arXiv. Differences in the properties of matter and antimatter,…

Evidence for CP violation in Λb0→ΛK+K– decays
This week, at a CERN seminar, the LHCb collaboration presented new results that provide evidence for CP violation in Λb0→ΛK+K– decays. LHCb is an experiment designed to study physics phenomena including “CP violation”, which is closely linked to the disappearance of antimatter soon after the Big Bang leaving only matter to survive and build the…

End of successful proton-proton collision data taking period
The 2024 proton-proton collision period at the LHC ended this week. This period was particularly successful for LHCb, also owing to the excellent performance of the LHC. The rate at which the experiment was able to acquire integrated luminosity was spectacularly higher than in previous years, as shown in the luminosity plots presented in this…
