End of the PbPb run and the 2025 run
One week ago the LHC dumped the beams for the last time this year, bringing the heavy ion run to an end. During this campaign, LHCb collected 0.86 nb⁻¹ of…
Precision measurements of CKM angle γ, charm mixing and CP violation
Today, at the CERN seminar, the LHCb collaboration reported an improved determination of the CKM angle γ with a precision of 2.6°. This result was obtained by a simultaneous combination…
End of the 2025 proton-proton collision run
The proton–proton (pp) data-taking period for 2025 has just come to an end. Thanks to the commitment and expertise of members of the LHCb collaboration, the outstanding performance achieved throughout…
The LHCb collaboration turns 30!
In August 1995 a Letter of Intent was submitted for the LHCb experiment, the world’s first dedicated B-physics experiment exploiting the unique potential of high-energy hadron-hadron collisions. This year, the…
Special light-ion LHC runs
The LHC carried out a special run programme early summer. First results were reported by the ALICE, ATLAS, CMS and LHCb experiments at the Initial Stages of High-Energy Nuclear Collisions…
Searching for new physics with the flavour changing neutral current decay B0→K*μ+μ–
Last week at the LHCC open session and this week at a CERN seminar, the LHCb collaboration presented the legacy results from Run-1 and Run-2 data of the angular distributions…
Observation of orbitally excited Bc+ states
At a CERN seminar today, the LHCb collaboration announced the first observation of orbitally excited Bc+ states, which are composed of a beauty-charm quark-antiquark pair. Within the expected mass range…
The first dedicated Z-boson mass measurement at the LHC
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…
LHCb Upgrade II Scoping Document
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 2025 Breakthrough Prize in Fundamental Physics awarded to the LHCb collaboration
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…
