New data-taking records for LHCb
Since March 30, the LHC accelerator has been operating in a special configuration, providing a lower collision rate to ATLAS and CMS than usual. This allows these experiments to complement their physics programmes, targeting a range of additional precision measurements. In this configuration, the so-called “burn-off” of the beams is much slower than usual, resulting…

Observation of the doubly charmed heavy proton Ξcc+.
Today at the Rencontres de Moriond Electroweak meeting, the upgraded LHCb experiment at CERN announced its first particle discovery: a new kind of heavy proton-like particle known as the Ξcc⁺. To appreciate what makes this particle special, it helps to recall how an ordinary proton is built. A proton contains three quarks – two up…

LHCb releases service to access Run II data
The LHCb collaboration is happy to announce the official release of the LHCb Ntupling Service: a web service for on-demand production and publishing of custom LHCb open data. This provides the public access to both Run I, and for the first time, Run II pp data collected by LHCb. This amounts to over 4 PB…

Chasing top quarks and Higgs bosons with Artificial Intelligence
Recently the LHCb collaboration published two papers reporting the use of Artificial Intelligence (AI) in the study of top quark and Higgs boson production. The use of AI allowed LHCb physicists to study top and Higgs decays into lighter quarks. Quarks are not observed directly in particle detectors; instead they fragment into collimated sprays (called…

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…
