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 family of doubly charmed baryons and adds a new chapter to a story that stretches back more than sixty years. The Ωcc+ was observed as…

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 LHC performance to collect 5.34 fb-1 of collision data. Almost all the data were taken at the highest LHC energy of 13.6 TeV. However, on…

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. 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.…
