Run 3: Sitting on a Goldmine
At the end of June 2026, LHCb recorded data from the last proton-proton collisions of LHC Run 3. The collaboration has now had time to take stock of what has…
Discovery of a beauty-strange particle with unexpected properties
The LHCb collaboration has just reported the observation of a resonance in the Bs0π0 invariant-mass spectrum with a global significance exceeding seven standard deviations at the 43rd International Conference on…
Precision measurement of the B0 and B+ lifetimes
The LHCb collaboration has just reported the measurement of the effective lifetime of the B0 meson in the decay B0→J/ψK*(892)0 and B+ meson lifetime in the decay B+→J/ψK+ at the…
Timothy Gershon and Paula Collins – new spokesperson team for the LHCb Collaboration
On 1 July 2026, the management of the LHCb collaboration is changing. The new spokesperson team of Tim Gershon (Spokesperson, University of Warwick) and Paula Collins (Deputy Spokesperson, CERN) will…
Observation of the doubly charmed baryon Ωcc+
In a major new discovery, LHCb has announced the observation of the doubly charmed Ωcc+ baryon at the Beauty 2026 conference in Maastricht. With this result, the experiment completes the…
Special LHC Low Energy Run – LHCb goes to space
LHCb is celebrating the end of a very strong proton-proton run in 2026, during which the experiment benefitted from the stable and efficient running of the detector and the excellent…
Lepton Flavor Universality Tests Using Bc+ Decays at LHCb
Today, at the CERN seminar, the LHCb Collaboration presented a new test of lepton flavour universality (LFU), one of the basic principles of the Standard Model (SM) of particle physics.…
A measurement of the CKM angle γ
LHCb has just submitted for publication a paper reporting a measurement of the CKM angle γ using the decay channels B±→DK± and B±→Dπ±, where the D meson decays to D→KS0…
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…
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⁺.…
