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…

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…
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
