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 PbPb collisions, almost double the sample collected last year, thanks to improvements such as the enhanced β* = 1m optics. At the same time, the…

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 of measurements sensitive to the CP-violating angle γ of the Cabibbo-Kobayashi-Maskawa (CKM) unitarity triangle, to the charm parameters describing oscillations (mixing) between D0 and D0…

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 entire pp run has been made possible. LHCb has successfully collected 11.8 fb-1 of high-quality pp data. The image on the left below shows…
