Heavy Ion collisions ended 2023 data taking period
The 2023 data-taking period ended this morning at 4 am. This year LHCb started taking data on April 14 with proton-proton collisions and ended today with lead-lead heavy ion collisions. This was the longest run with lead ions in the LHC and it was also the first one after five years. Lead ions are large…

Second life of the LHCb’s Outer Tracker at GSI
The Outer Tracker (OT) is the largest component of tracking system in the original version of the LHCb detector. It was replaced by the Scintillating Fibre (SciFi) sub-detector in the upgraded detector that is taking data in Run 3. The OT was just transported to GSI in Darmstadt, Germany, in order to be used in…

New observation of hypertriton and antihypertriton production in LHC proton-proton collisions
Today, at the European Physical Society Conference on High Energy Physics (EPS-HEP), the LHCb Collaboration reported its first observation of hypertritons and antihypertritons using Run 2 data collected between 2016 and 2018. About 100 such hypernuclei were spotted. Hypertritons, 3ΛH, were reconstructed via two-body decays into helium nuclei and pions. The key features of the…
