Today, the LHCb collaboration submitted for publication a paper reporting the first dedicated Z-boson mass measurement at the LHC using Z→μ+μ− decays. The data were recorded in 2016 and correspond…

The scientific review of the LHCb Upgrade II Scoping Document has been concluded by the LHC Committee, and the CERN Research Board has endorsed their conclusions reaching in this way…

The LHCb collaboration has been awarded yesterday the 2025 Breakthrough Prize in Fundamental Physics, together with the three other CERN’s Large Hadron Collider collaborations: ALICE, ATLAS and CMS, “For detailed…

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…

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…

The LHCb collaboration submitted today a paper reporting new tests of lepton flavour universality, one of the cornerstone of the Standard Model (SM) of particle physics. It implies that the…

The LHCb collaboration submitted today a paper reporting precise measurements of the mass values and splittings of the hidden-beauty particles that exist within the bb quark bound system called bottomonium.…

Today, at the 42nd International Conference on High Energy Physics, ICHEP, Prague, Czech Republic, the LHCb collaboration reported a measurement of the effective leptonic weak mixing angle, sin2θleff, the parameter…

Today, at the 42nd International Conference on High Energy Physics, ICHEP, Prague, Czech Republic, the LHCb collaboration reported an improved determination of the CKM angle γ with a precision better…

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.…
