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…
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…
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…
LHCb data released to the public
Today the LHCb collaboration has, for the first time, released its data to the public allowing research to be conducted by anyone in the world. All scientific results from the…
First VELO closing
Today the two halves of new Vertex Locator (VELO) approached the LHC proton-proton collision point for the first time. This process is called “VELO closing” in the LHCb jargon. The…
New test of lepton universality using the first simultaneous measurement of R(D) and R(D*) observables at LHCb
[ R(D*) = 0.281±0.018±0.024 ][ R(D) = 0.441±0.060±0.066 ] Today at the CERN seminar the LHCb Collaboration presented new tests of lepton universality, one of the basic principles of the…
The first evidence for CP violation in a specific charm hadron decay
The International Conference on High Energy Physics, ICHEP 2022, ended today in Bologna (Italy). At this conference, the LHCb collaboration reported a new measurement of the CP-violating asymmetry, ACP, in…
First collisions at the world-record energy for a brand-new LHCb detector
Start of LHC Run 3. Today, at 16:47, protons collided again at LHCb after a 3.5 year break known as Long Shutdown 2 (LS2). During this period the original LHCb…
Observation of a strange pentaquark, a doubly charged tetraquark and its neutral partner.
Today, at the CERN seminar, the LHCb Collaboration reported the observation of a strange pentaquark, a doubly charged tetraquark and its neutral partner. These results will also be presented at…
Measurement of the CKM angle γ
The largest CP violation ever observed. This week, at the 10th Annual Large Hadron Collider Physics Conference, LHCP2022, LHCb presented results of the determination of the Cabibbo–Kobayashi–Maskawa (CKM) angle γ…
