Upstream Tracker closing completes installation of the LHCb Upgrade 1 detector
Start of 2023 data taking. Recently the Upstream Tracker (UT), a sub-detector of the LHCb experiment, was closed around the LHC beam pipe. This event marked the completion of the installation of the LHCb Upgrade1 detector. The UT sub-detector is located in front of the LHCb dipole magnet, as seen in the schema displayed at […]

Test of Lepton Flavour Universality using a measurement of R(D*) with hadronic τ decays
Today, at the CERN seminar, the LHCb Collaboration presented a new test of lepton universality, one of the basic principles of the Standard Model (SM) of particle physics. This principle states that the SM treats the three charged leptons (e, μ and τ) identically, except for kinematical effects due to their different masses. In this […]

Inauguration of the LHCb exhibition
Today a brand new LHCb exhibition was inaugurated at a gathering of LHCb collaborators and members of the CERN Education, Communications and Outreach team. The exhibition, which is located in the surface experimental hall 100m above the detector, tells the story of LHCb, allowing visitors to see parts of the experiment up close and go […]

LHCb’s unique approach to real-time data processing
The LHCb collaboration is currently enhancing its unique system of data filtering, Real Time Analysis, by installing a 2nd set of Graphics Processing Units (GPUs) in the trigger system. Current technology does not allow all LHC proton-proton collision data to be stored and analyzed. A fast event selection procedure, referred to as trigger, is therefore […]

Improved lepton universality measurements show agreement with the Standard Model
Today at the CERN seminar the LHCb Collaboration presented new tests of lepton universality, one of the basic principles of the Standard Model (SM) of particle physics. This principle states that the SM treats the three charged leptons (electrons, muons and taus) identically, except for differences due to their different masses. The results are in […]
