Journal ArticleDOI

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

LHCb detector performance

Roel Aaij, +703 more
TL;DR: In this paper, the performance of the various LHCb sub-detectors and the trigger system are described, using data taken from 2010 to 2012, and it is shown that the design criteria of the experiment have been met.
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

Performance of the LHCb RICH detector at the LHC

TL;DR: The RICH system provides charged particle identification over a wide momentum range, from 2–100 GeV/c, and excellent separation of hadronic particle types (π, K, p) is achieved.
