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…
Probing the nature of the mysterious particle χc1(3872)
Today, at a CERN seminar, the LHCb collaboration reported precise measurements of the properties of the mysterious particle χc1(3872), also known as the X(3872), using radiative decays χc1(3872)→ψ(2S)γ and χc1(3872)→J/ψγ.…
Observation of the rare Σ+→pμ+μ– decay
The LHCb collaboration reported the observation of the Σ+→pμ+μ– rare decay at the XV International Conference on Beauty, Charm, Hyperons in Hadronic Interactions (BEACH 2024) in Charleston, South Carolina, USA.…
ECAL and RICH sub-detector enhancements approved for construction
The LHCb experiment will upgrade the inner part of the Electromagnetic Calorimeter and the electronics of the Ring Imaging Cherenkov detectors in the next LHC Long Shutdown (LS3). On July…
LHCb observes the rare decay J/ψ→μ+μ–μ+μ–
Today, at the Rencontres de Moriond QCD and High Energy Interactions, the LHCb collaboration reported the observation of the rare elecromagnetic decay J/ψ→μ+μ–μ+μ–. The simultaneous discovery of the J/ψ meson…
Ruhr-Universität Bochum became LHCb’s 100th collaborating Institute
In February 2024, the Ruhr-Universität Bochum became 100th institute to join the LHCb collaboration. We have come a long way since August 1995, when a Letter of Intent was submitted…
