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…

[ mW=80354±23stat±10expsys±17theory±9PDF MeV] 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…

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. [R(D*) in this measurement = 0.291±0.019±0.029; LHCb average =…

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…
