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.…
Test of lepton flavour universality with Bs0 → ϕℓ+ℓ− decays
The LHCb collaboration submitted today a paper reporting new tests of lepton flavour universality, one of the cornerstone of the Standard Model (SM) of particle physics. It implies that the…
New tests of lepton universality with τ leptons
Today at the 30th International Symposium on Lepton Photon Interactions at High Energies, organized by the University of Manchester, the LHCb Collaboration presented new tests of lepton universality, one of…
New tests of lepton universality show the same pattern as deviations seen in previous results
Test of lepton universality using B0→KS0l+l– and B+→K*+l+l– decays. Today at the CERN seminar and at the Rencontres de Blois the LHCb Collaboration presented new tests of lepton universality, one…
The first LHCb measurement of the W boson mass
Last week the LHCb Collaboration submitted for publication a paper that reports the first LHCb measurement of the W boson mass with an uncertainty of 32 MeV using the 2016…
New test of lepton universality
Measurement of R(D*): the ratio of branching fractions between B0 → D*-τ+ντ and B0 → D*-μ+νμ using three-prong hadronic τ decays. Yesterday, at the 15th Flavor Physics and CP violation…
Lepton universality test probes physics beyond the Standard Model
LHCb finds new hints of possible deviations from the Standard Model. Today, at a seminar at CERN, the LHCb collaboration presented results on the measurement of RK*0, which is the…
