  • The first evidence for CP violation in a specific charm hadron decay

    The first evidence for CP violation in a specific charm hadron decay

    The International Conference on High Energy Physics, ICHEP 2022, ended today in Bologna (Italy). At this conference, the LHCb collaboration reported a new measurement of the CP-violating asymmetry, ACP, in the decay of neutral charmed mesons, the D0, into a pair of charged kaons, D0→K–K+. This result followed the exciting result of March 2019, in […]

  • First collisions at the world-record energy for a brand-new LHCb detector

    First collisions at the world-record energy for a brand-new LHCb detector

    Start of LHC Run 3. Today, at 16:47, protons collided again at LHCb after a 3.5 year break known as Long Shutdown 2 (LS2). During this period the original LHCb experiment has been largely dismantled and an almost completely new detector has been constructed. At the same time improvements of the LHC collider allowed it […]

  • Observation of a strange pentaquark, a doubly charged tetraquark and its neutral partner.

    Observation of a strange pentaquark, a doubly charged tetraquark and its neutral partner.

    Today, at the CERN seminar, the LHCb Collaboration reported the observation of a strange pentaquark, a doubly charged tetraquark and its neutral partner. These results will also be presented at the ICHEP 2022 International Conference on High Energy Physics in Bologna, Italy, starting tomorrow. The pentaquark, PΛψs(4338)0, is observed with high significance in the J/ψΛ […]
