The LHCb detector at the LHC

A. A. Alves, +889 more
TL;DR: The LHCb experiment is dedicated to precision measurements of CP violation and rare decays of B hadrons at the Large Hadron Collider (LHC) at CERN (Geneva).
Journal ArticleDOI

Test of lepton universality using b^{+}k^{+}ℓ^{+}ℓ^{-} decays

Roel Aaij, +701 more
TL;DR: The value of the ratio of branching fractions for the dilepton invariant mass squared range 1 < q(2) < 6 GeV(2)/c(4) is measured to be 0.745(-0.074)(+0.090)(stat) ± 0.036(syst).
Journal ArticleDOI

Measurement of form-factor-independent observables in the decay B0→K*0μ+μ-

Roel Aaij, +656 more
TL;DR: A measurement of form-factor-independent angular observables in the decay B(0)→K*(892)(0)μ(+)μ(-) is presented, based on a data sample collected by the LHCb experiment in pp collisions at a center-of-mass energy of 7 TeV.
Journal ArticleDOI

Test of lepton universality with B 0 → K *0 ℓ + ℓ − decays

Roel Aaij, +821 more
TL;DR: In this article, a test of lepton universality is performed by measuring the ratio of the branching fractions of the B$0$ → K$*0}$ e$+}$ π$−}$ decays, and the ratio is measured in two regions of the dilepton invariant mass squared.
Journal ArticleDOI

Measurement of the Ratio of Branching Fractions B (B ¯ 0 →d∗+τ- ν ¯ τ) / B (B ¯ 0 →d∗+μ- ν ¯ μ)

Roel Aaij, +723 more
TL;DR: In this paper, the branching fraction ratio of the tau lepton was measured at the LHCb collider, which is 2.1 standard deviations larger than the value expected from lepton universality in the standard model.
