Journal ArticleDOI

Observation of $J/\psi p$ Resonances Consistent with Pentaquark States in $\Lambda_b^0 \to J/\psi K^- p$ Decays

Roel Aaij, +722 more
TL;DR: In this article, the pentaquark-charmonium states were observed in the J/ψp channel in Λ0b→J/K−p decays and the significance of these resonances is more than 9 standard deviations.
Journal ArticleDOI

Test of lepton universality with $B^{0} \rightarrow K^{*0}\ell^{+}\ell^{-}$ decays

TL;DR: In this paper, a test of lepton universality, performed by measuring the ratio of the branching fractions of the $B^{0} \rightarrow K^{*0}\mu+}\mu^{+}e^{-}$ decays, is presented.
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.
Journal ArticleDOI

Search for Lepton-Universality Violation in B + →K + ℓ+ ℓ- Decays

Roel Aaij, +861 more
TL;DR: This is the most precise measurement of R_{K} to date and is compatible with the standard model at the level of 2.5 standard deviations.
